<s>[INST] I have a pattern rash on my back they are round and red they are on a diamond grid pattern. I have noticed this for a couple of days. its not itch but now it feels kind of warm I didn t sit on anything strange and the last thing that I did was polling weeds in the garden I am taking some cranberry pills with olive leaf and corn silk no other medication Any thought of what it could be? [/INST] Hi,It may be contact allergic dermatitis. Kindly consult the dermatologist for the perfect diagnosis and proper treatment.I would suggest to take oral steroid in tapering dose for few weeks. And apply mild steroid cream mixed with antibiotic.Avoid contact with suspected allergens.Thanks.Dr.Ilyas Patel MD </s>
