I have a bilateral rash that comes and goes. It mostly comes after a shower. I am on an antibiotic now for a bacterial infection I got after plastic surgery . Tomorrow is the last day of the antibiotic. At first when I started taking the antibiotic,augmenting the rash went away. Tonight after I showered it came back on both sides of my trunk. What do you think it is?
Hi there. I read your problem with interest, but it does seem some form of physical or heat/cold induced urticaria. Dermatology however, is a very visual line & as such, requires some clear visual digital photographs or to be seen on the ground by a dermatologist nearest you for best results! Please take a non-sedative antihistamine namely 180 mg fexofenadine taken once a day that is safe but may require a prescription in your parts. Worst case scenario is that a skin biopsy may be required to help clear the diagnosis & for further management. Cheers & Godspeed!  Chat Doctor.
