<s>[INST] I have an itchy scalp severe and a rash on my chest also that itches. I have been to the doctor already several times and I still have it . the doctor prescribed shampoos, creams and stuff for your scalp and even antibiotics. I think the only time I was helped was with the antibiotic. what should I do? [/INST] Hi.As per your case history you are having fungal infection called as tinea corporis.My treatment advice is – 1. Maintain good hygiene and bath twice daily.2. Apply an antifungal cream like clotrimazole cream twice daily on it.3. Take an antihistamine like levocetirizine for 7-10days .4. Other treatment options are oral fluconazole, itraconazole and terbinafine  given only after consulting a dermatologist.Thanks.Dr.Harshit Bhachech.MBBS, DDVL. </s>
