### input:
hello doctors,first off thank you for your time and service. i have recently been having this raised blotchy rash that is itchy and the color is slighty red/pinkish(im african american not very dark or light skinned). i believe the rash started mid last month and would come and go. originally it began on the torso never on my chest area but both sides of my serratus anterior. then there was a week or two where it hadnt appeared at all. about a week and a half ago it started again but on my upper outer thigh area, and yesteday it began on my neck. it gives me reason for concern that i may have hiv. i say this because i believe i may have been at risk in early feb and within a week of possible exposure the lymph node in my groin swelled up and it eventually started to hurt alot but this only lasted for a week and then appearantly it ruptured and this milky smelly fluid leaked out for 2-3 days. after that no more groin problems just an occasional sore throat but around that time i had been in contact with a few sick people so dont know if the signs are related to my concern. anyway the rash is consistent and would like to know what you think and if there is anything information you may need please ask.

ChatDoctorplains of raised blotchy itchy rasChatDoctoring on and off suggests you have urticaria. If duration of symptoms is less than six weeks than we call it acute urticaria and if it is more than six weeks we call it chronic urticaria. Duration and line of treatment will depend on severity of the disease condition. Oral antihistamines usually help but occasionally oral steroids may need to be given. Blood investigations like serum IG e level may be needed to be done, decision being case specific. Hope this helpsFurther information can be provided by your dermatologist only after examining the area. Regards Chat Doctor.
