I am having rash frequently, got my blood test done it was normal. Doctor told that rash must be due to some hidden allergy or it must be due to stress. I am scared that i might have hiv. how to differentiate whether my rashes are stress rashes or hiv rashes. I am attaching some pictures so that you get to know what are these rashes all about . Moreover they are itchy red rash. The rashes started in the month of December during which i was taking alot of stress for my board exam. Stress must be a reason .but i am just worrying what if it's hiv . Please respond with utmost preciseness.
