Most likely it is just an aphthous ulcer or a canker sore. They are usually found on on movable tissue and self resolve after 14 days. It wouldn't hurt to get a dentist to look at it.

Contagious itchy skin with no rash until scratched?

Some thoughts...

Without a picture it's very difficult to diagnose a skin condition, and what you're describing can have many different causes. It could be a mild eczema, a fungal infection, a viral exanthem, a reaction to something you've come in contact with (a new perfume, lotion, soap), bug bites... it's a long list. If OTC hydrocortisone or benadryl isn't helping, make sure to check in with your doc!

I have a rash that looks like goosebumps and is very itchy on my back upper arms? What is this and is it contagious

You probably have a skin condition called keratosis pilaris which is a benign chronic condition. Treatment consists of moisturizing cream and, occasionally, hydrocortisone cream. Once in a while, using an exfoliant may help.
