Some netizens said that this may be allergic purpura . They had suffered from it before and it looked like this.
Some netizens also said that
their skin also appeared abnormal after becoming masculine.
Chief physician Qiao Jianjun, deputy director of the Dermatology Department of the First Hospital of Zhejiang University, said that infection with the new coronavirus can cause a systemic immune response and bring about some skin manifestations. Some of these patients are related to viral infections, such as pityriasis rosea, urticaria, allergic purpura, etc.; some are caused by taking drugs.
This is a patient with chronic urticaria who originally had well-controlled chronic urticaria . After positive fever, the whole body rash suddenly worsened and evolved into acute urticaria.
According to health news in Hangzhou, many people in Hangzhou have recently been diagnosed with drug eruption caused by drug allergies.
Common allergy-prone drugs
Antibacterial drugs: such as penicillin, erythromycin , sulfonamides, cephalosporins, isoniazid , fluconazole , etc. With the standardized application of antibiotics and the improvement of awareness of antibiotic allergy, the incidence of allergies caused by antibiotics has decreased.
Non-steroidal anti-inflammatory drugs: acetaminophen , ibuprofen , aspirin, indomethacin, etc. Drug eruptions caused by these drugs are more common, ranging from fixed drug eruptions to urticaria type or even toxic epidermal necrolysis type drug eruptions.
Sedative-hypnotic anti-epileptic drugs: phenobarbital, carbamazepine , etc.
serum preparation and vaccine .
Dr. He Shunv from the Department of Dermatology, Linping District Hospital of Integrated Traditional Chinese and Western Medicine, said that many -positive friends will develop rashes, and antipyretics and antibiotics can easily cause allergies. If allergies occur after taking the medicine, you should stop taking the allergy medicine immediately and drink more water. If the rash worsens, or if chest tightness, shortness of breath, abdominal pain and other discomforts occur, you should go to the hospital for anti-allergic treatment in time to avoid worsening of the condition.
Chief Physician Qiao Jianjun reminded that if the rash is unbearably itchy and affects daily life or physical health, you need to go to the hospital as soon as possible and take targeted medication.
In addition, patients who develop drug rash due to taking relevant drugs should use drugs rationally according to their symptoms and drug indications, pay attention to changes in their bodies at all times, and seek medical treatment in time if any abnormalities occur.
In addition to skin abnormalities, many people have recently reported eye pain and decreased vision due to "yang"
"My right eye was red for 3 days after becoming positive, and my tears increased significantly."
"After I recovered from the fever, my left eye was blurry and my sensitivity to light was obvious"
"I saw things a little blurry 2 days after I tested positive"...

If you experience eye discomfort after being infected with the new coronavirus
You can use cold compress to relieve eye pain and other discomforts
If the discomfort persists
You should go to the hospital in time
Deputy Chief Physician of the Department of Ophthalmology of Beijing Geriatric HospitalMr. Zhao Huiying said that after infection with the new coronavirus, redness, eye pain, and decreased vision are relatively common eye discomforts.
Conjunctivitis is the most common ocular manifestation after COVID-19 infection. Patients mainly present with discomfort such as red eyes, foreign body sensation, and tearing. The disease can occur in one or both eyes and can occur at various stages of COVID-19 infection.
"It is currently believed that the occurrence of conjunctivitis may be related to the new coronavirus directly invading the conjunctival tissue or the immune system attacking the conjunctival tissue after the new coronavirus infects the body. Hand-eye contact may increase the occurrence of conjunctivitis."
Superficial scleritis can also be seen in patients with new coronavirus infection, manifesting as local redness, eye pain, tearing and other discomforts. Zhao Huiying said that most superficial scleritis is self-limiting, and previous studies have shown that about 1/3 of patients with superficial scleritis may be related to viral infection. Uveitis, keratitis can also cause redness in patients infected with the new coronavirus. In addition, because the new coronavirus activates inflammatory factors and causes trigeminal nerve dysfunction, people with positive infection may also experience eye pain.
Central retinal vein occlusion is one of the many vascular diseases caused by the new coronavirus infection. Patients may experience blurred vision, distorted vision, etc. Central retinal artery occlusion can also occur in people infected with COVID-19. The main manifestation is sudden painless vision loss. In addition, patients infected with COVID-19 may also develop acute macular neuroretinopathy due to fundus capillary ischemia, manifesting as painless vision loss or visual obstruction in one or both eyes.
What should we do if eye discomfort
occurs after "Yang"?
doctors remind that the primary disease should be actively treated first, such as eye pain associated with high fever, and antipyretic drugs need to be used according to the doctor's instructions. Applying cold compresses to the eyes can be used to relieve discomfort such as eye pain. If vision loss occurs, you should go to a medical institution with ophthalmology in time to avoid delaying treatment.
Patients with persistent discomfort such as eye redness and eye pain should also go to a medical institution for treatment. Hand-eye contact may increase the occurrence of conjunctivitis, so try to avoid rubbing your eyes with your hands to avoid eye infection.

Many people become allergic after taking antipyretics! Doctors remind
that the current COVID-19 is mostly a self-limiting disease caused by the Omicron strain. Most of the symptoms are fever, sore throat, muscle aches, cough, etc. In addition to resting and drinking more water, antipyretic and analgesic drugs have become essential medicines to relieve symptoms.
Xie Yang, deputy chief physician of the Dermatology Department of Zhongshan Third Hospital, said that because people do not know much about skin allergies caused by antipyretic and analgesic drugs, there has been a significant increase in patients with drug eruptions (drug-induced dermatitis) caused by these drugs in dermatology outpatient clinics in recent days. "Although most drug eruptions are mild, if the allergenic drugs cannot be identified early and continue to take allergenic drugs, it may induce life-threatening severe drug eruptions, as well as visceral damage such as liver and kidneys."
According to reports, theoretically all drugs may cause skin allergies, but antipyretics and analgesics are one of the most common drugs that cause drug-induced dermatitis in clinical practice. But there is no need to panic, because drug allergic reactions are only seen in a small number of people with allergies and .
Faced with the dazzling array of antipyretics
how should we avoid
drug allergies?
Dermatologist
of Zhongshan Third Hospital has a few suggestions:
1. Friends who have no history of allergies should give priority to an antipyretic drug that they have often taken in the past. If the drug has been used more than twice in the past, generally speaking, the possibility of drug allergy is low.
In addition, the medication plan should be as simple as possible, and it is not recommended to use similar drugs together. For example, ibuprofen and acetaminophen are both antipyretic and analgesic drugs, and you only need to choose one; antiviral oral liquid and isatis granules are also similar drugs, and there is no need to use them together.
2. Friends who have ever had drug allergies need to pay special attention! Especially for patients who have been allergic to antipyretic drugs in the past, they may immediately experience a drug allergic reaction if they take drugs of the same type or similar structure again. It is recommended not to use them as much as possible, or to use other non-allergic drugs first. If necessary, consult the hospital online or see a doctor, and the doctor must be clearly informed of the previous medication and allergy symptoms.
3. Early identification: There are also many patients who do not know whether they have a history of drug allergies, or patients who have clear allergies but have never been allergic to antipyretics. At this time, attention should be paid to early identification of drug-induced skin allergic reactions during the oral administration of antipyretics.
Drug-induced dermatitis usually has an incubation period, which means that the rash will appear after taking medicine for a period of time. The length of the incubation period is related to the nature of the drug. If the allergenic drug has never been used before, the incubation period may be a few days or even a week; but if the allergenic drug has been used once before, the incubation period may be as short as a few hours. Therefore, you should be alert to any drug allergies within a week after taking the medicine!
4. Early treatment: Once you encounter a sudden rash while taking medicine, you need to be vigilant on the one hand, but you don’t need to panic on the other hand, because most drug eruptions are mild.
At this time, stop using the suspected drug immediately, and it is best not to take other drugs to prevent cross-allergy or polyvalent allergy (that is, in addition to allergenic drugs, other drugs with similar structures or even previous non-allergic drugs may aggravate allergies at this time);
At the same time, increase drinking water appropriately to promote the body's The remaining drugs are excreted;
If the itching is obvious, you can take oral antihistamines such as cetirizine, ebastine, etc. The choice of topical drugs is closely related to the shape of the rash and requires the guidance of a doctor. Therefore, if there are more serious symptoms or a high fever that cannot go away, it is still recommended to go to the hospital for treatment.
5. Advocate for scientific medication:
① The new coronavirus is a viral infection. In most cases, there is no need to use antibacterial drugs together, so the cephalosporins at home can be put away first;
② Low and moderate fever below 38.5℃ can usually be relieved by drinking more water. Unless you feel very bad, you don’t have to rush to take antipyretics;
③ Read the instructions carefully before taking the medicine, and take it orally according to the dose and time interval. Antipyretic and analgesic drugs take effect in varying lengths, so do not increase the dosage on your own in a hurry.
