I have severe itching on my chest area most days but not every day... its been a year i have a feeling its not allergy? i've tried switching all soaps

Please see below.: It could be eczema or a contact dermatitis. Use a hypoallergenic skin cleanser, avoiding bathing in very hot water, and use a hypoallergenic skin lotion at least 3 times daily, even if there's no rash. Add Hydrocortisone 1% ointment (otc) and an oral antihistamine like zyrtec (cetirizine) if needed. If doing this doesn't help enough, please see the doctor.

Many possible causes: There can be numerous causes of itchy. Some relatively benign and some more severe. A thorough evaluation by a physician should help one understand the cause.
