Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
You are 42 yrs, You have mild asthma
and allergies, it starts as a small red mark and progress . Never itchy, and never at the same place.
It is a mild allergy
, caused by allergens found in the winter. If you take care in the winter you will be fine. If you can find the allergen, like winter fruits, flowers, wool, etc, you may not get it at all.
If you feel it uncomfertable you can consult a physician for diagnosis and treatment.
Wishing for a quick and complete recovery.
