I have a rash in my arm that started about a month ago only as what i thought were mosquito bites or maybe a smallnspider since they were forming almost a full circle, they went away by them selves, since then they have come and gone 2 more times, but this time they got bigger itchier and they have now joined togeather in a half circle shape leaving a very red very itchy and bumpy patch.... Its only this and alwys in exactly the same place!!! Could it be some alergic reaction yo a bug bite?
Hi, The rash could most probably an urticaria. Other conditions such as Tina, Popular urticaria etc. could be ruled out after proper examination by a Dermatologist.  You could take an antihistamine tablet for a week. If you do not get improvement in a week or if your symptoms worse during the course, you must consult your Dermatologist for proper management. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
