<s>[INST] hi i am 40 years old and for six months having problems with allergic reactions. my test results show that i have a 792 allergy. i am getting rash all over my body but most in the face and chest. i am using diprofros injection for 4 months once a month sometimes every 3 weeks. do i have to take this for the rest of my life or is there something else i can do? to avoid the use of diprofros? [/INST] Hello. Thank you for asking at Chat Doctor. I went through your history and from your history I think you may have what we call "chronic urticaria". It is important to identify the cause of chronic urticaria, it is not always allergic. So I would like to ask you in detail about possible causes like excessive sweating, sun exposure, contact with hot/cold water, any Chat Doctor.  And I would also suggest you investigations like CBC, ESR, CRP, thyroid tests, urine & stool examination. If these investigations reveal any cause, I would treat the cause. If these do not reveal any cause, I would suggest you to consult an Allergist who will ask you in detail and suggest you further investigations to look for cause of urticaria. Till your cause is identified, I would suggest you to take Levocetirizine in morning and Montelukast and HY </s>
