I have a small "pimple" like bump on the tip of my tounge. It's more irratating then painful... But im worried. Any thought on what it may be?

Clogged taste bud. Most likely a minor malformation/clogging of a taste bud called fungiform papilliae, very much like a tiny pimple. This should resolve in a few days to maybe 2 wks. Aphthous ulcers are typically quite painful eventhough they are often quite small. If it is not gone in 2wks, check with your doc.
