I have a small growth or bump on the flap of skin, or just behind, in my throat before my tonsils. It is about the size of a pea. It appears to be the same color as all other tissue in my throat. I've just noticed it in the past two days. Should I be concerned? Should I see a specialist? It isn't very painful but more aggrivating. When my throat is dry it is causing me to want to cough.
