Hi, I tested positive for COVID on May 4th but didnt have any issues for about 2.5 weeks after that. Recently, Ive noticed an allergy around the corners of my mouth. I tried applying Sebamed lip balm in the morning and Laneige lip sleeping mask at night, but the irritation spread to my upper and lower lips. I switched to using Vaseline petroleum jelly, but now theres swelling in my lips, a burning sensation around my mouth, and a rash on my face. Could you help me figure out whats going on and what I should do?

Sounds like you may be experiencing an allergic reaction or contact dermatitis. I recommend stopping the use of all lip products and petroleum jelly for now. You can take an antihistamine such as Cetirizine to help with the itching and swelling. Additionally, you can apply a thin layer of hydrocortisone cream 1% on the affected areas of your lips and face twice a day for up to 7 days. Make sure to avoid any known allergens or irritants, and if the symptoms persist or worsen, please consult a dermatologist for further evaluation and management.
