On both of my arms I have red bumpy skin it doesn't itch its just really embrassing what can I do to treat it?

BUMPY ARM SKIN. Cannot tell with out seeing what you have. It sounds like a condition called keratosis pilaris. Have a dermatologist check it out. There are several salves and lotions that can help this.
Keratosis pilaris. Chronic dry skin , rough to touch, embarrassing like you said.Best recommendation is to use apricot scrub and any moisturizing cream or lotion.Takes a long time to clear but will eventually resovled through time.
Get seen. If you are embarassed by the rash, see your physician. It can probably be treated but that is not possible over the internet.
