instruction: hi doctor I am a year old male my weight is 180 labs and height is 10 I was prescribed a generic brand of adderall 20 my about a year ago it truly has improved my lifestyle up until about two months ago everything was fine I noticed that on the left side of my neck became red randomly I would describe it as looking more like a heat rash that starts around my collar goes up only on the left side of my neck it extends to my left ear and sometimes I get some redness on my left cheek bone it does not itch or bother me in any way but it is very noticeable sometimes I have not been able to find any other factor that could be causing this I have tried not eating particular foods changed my laundry detergent etc my older brother and I both get a redness in our face when we play sports and this has happened every since I can remember I do occasionally smoke cigarettes and have tried different brands to see if that may have a factor but nothing I have been to my local doctor and they have said that it is probably allergies but I just do not agree I am not allergic to anything but I have not got around to getting an allergy test since the redness appeared I am very concerned about this and more embarrassed thank you for any advice
output: hi I have read your concern and I appreciate your effort for a detailed and meticulous history revert back after seven days to a dermatologist online
