Hi Dear,
Welcome to HCM.
Understanding your concern.
Thanks for your query . The symptoms you mention in query is indicating
sun allergy or photosensitive reaction of skin towards UV rays of sun. It is also known as solar
urticaria .
These are not
cold sore as cold sores do not cause symptoms you mention in query.
I would suggest you to:-
- Give cold compresses to 2-3 times a day .
- wash your face twice a day to keep lips clean .
- Avoid sun exposure .
- Apply lip balm containing broad spectrum sunscreen containing SPF 15 throughout the day time even if you are not under sun exposure.
- Take over the counter antihistamine drug like benadryl .
If condition doesn't resolve or get worse in 3-4 days then
consult dermatologist for proper examination and rule out causes like fordyce's granule , acne ,
contact allergy or infection.
Doctor may prescribe corticosteroid ointment , beta carotinoids or antibiotics depending upon your condition.
Hope your concern has been resolved.
Get Well Soon.
