Rash In Inner Arms, Waistline, Lower Back. Suggest Treatment

thanks for the query
Rash can be caused by various conditions. Such conditions include infections (bacterial, fungal and viral), hyper-sensitivity/allergic reactions and irritation from substances in contact with the skin.
Bacterial infections are acute and rapidly evolving, easily contagious and will spread to another location if a finger used to touch a rash is used on a healthy area. Generally, the rash is reddish, may be filled with pus, or may have small dripping wounds.
Fungal infections turn to be chronic. Candida infections turn to affects mostly areas of skin fold and humid areas. The armpit, waistline (especially in fat individuals with folding of abdominal wall) and groin or inguinal regions are frequent places for Candida infection.
Viral infections are symmetrical and may be localized or spreading. They may present as fluid filled bumps.
Hypersensitivity reactions will be location specific in case of reaction to a local irritant or could be generalized in case of a systemic or ingested irritant.
Atopic dermatitis is common in people with family history of allergy or asthma or hives etc. It presents symmetrically and has a re-occurrence pattern occuring on a particular time in subsequent years.
In your case, the characteristic occurrence on the inner arms and waistline makes it more likely to be fungal in origin and antifungal such as ketoconazole, terbinafide, griseofulvin etc will help. However, only an appropriate physical examination will give definite diagnosis.Thus you might consider seeing your doctor for physical examination and possible tests.
