I'm not sure if this is the right place to post my question, but I will truly appreciate if I can get any help or answer.
So for the last 5 months, I have been experiencing these red rashes that appear on my skin and then vanish in a few minutes to half an hour or so. The rashes are usually confined to my upper body and that too specifically torso (back, stomach and chest). The rashes are slightly raised, red in color and appear in the form of thin streaks, usually slightly itchy. There was this one time when almost my entire back was covered in it and then they disappeared in like 45 minutes.
I am really getting concerned as to what is really going on with me and it just adds to my anxiety. please help or advise.
