<s>[INST] I am having red rashes all over my body. They look like red welts.  It started 2 days ago and while it has not increased it also does not seem to be reducing as well. I have red patches on my back, on my thighs, neck, chest, stomach. There is slight pain in my lower vertebrae as well. I have been using cortizone 10 regularly but except for temporary relief ther is no improvement. I used a new shirt 2 days ago, I travelled by plane to another city and have been eating out regularly. Canyou please tell me the probable cause and solution. [/INST] HI, I THINK UR RASH IS RELATED TO UR SHIRT.AS IT IS PRESENT IN THE SHIRT WORN AREA.IT CAN BE DUE TO CLOTH DERMATITIS.SOME KIND OF CLOTHES WILL BE ALLERGIC TO FEW PEOPLE.IT THINK RASH IS LIKE ERYTHEMATOUS PAPULAR ERUPTIONS OVER THE MENTIONED AREAS.USE A ANTIHISTAMINE IN NIGHT,ANTIBIOTIC AND APPLICATION OF CALAMINE LOTION IN THE MORNING AND FLUTIVATE OINTMENMT IN THE NIGHT CAN CURE IT </s>
