<s>[INST] I was travelling for 3 days last week and could not find space for bath. After that (Four days before) I started itching on some parts of my body chest area perhaps and unknowingly I scratched, upon which I found the next day it s like a ringworm, round shape rashes. It spreads also first just like a pimple that itches and then becomes bigger and round. I was using itchguard for last 4 days and I can t make out it s better or not. Is it okay to use quadriderm RF. Kindly suggest me. [/INST] Hi, Itchy rashes on chest could be due to Tina corporal or tricolor(a type of ringworm), candidiasis,contact dermatitis or psoriasis etc. Treatment is mainly depended on the underlying cause and for that these rashes must be seen by dermatologist to get diagnosed first. You may require oral and topical corticosteroids (beclomethasome, clobetasol propionate, mometasone)in combination topical antifungal cream like fluconazole or itraconazole along with antihistamines and strict hygiene. So, better you go to dermatologist. Thanks. </s>
