Thanks guys. I went to an oral surgeon today. He spent alot of time looking at every part of my mouth and tongue and did an xray and said there is nothing. He said what I perceive as a growth is some part of my tongue that might have been a little irritated and so flamed up a little. It looked like a growth to me and i feel it touching against back of my mouth/throat but whatever.

So, what do you guys think? Always get a 2nd opinion or should I let it go? I'm supposed to go for a follow up next week with him (he gave me antibiotics in the meantime).

This is a pic of it (circled area):
