I keep getting some or another health issues like fungal infection, my back neck itching isn't gone even after 4-5 months of treatment oinment and tablets it gets better but then before getting completely heal it starts itching again. Itching is spreading in back. I got bad cough for about 2 weeks and then my lower chest started paining and it's been a month, it has reduced after starting vitamin B-12 but not completely. I also get alot of acne on my face. I don't understand what's wrong and what should I do.
