Painful bumps on my my tongue, please help ?

I've been getting small painful bumps - not much bigger than taste buds - on my tongue. About three weeks ago, I had them on the side of my tongue towards the front, and now they've migrated to the front and only a bit of the sides. They're very painful, and they could just be swollen taste buds. The reason I'm wary about them being swollen taste buds is because I've had them for three weeks and they don't seem to be healing, in fact, the pain is getting worse. I don't do drugs, smoke, drink, and they are not an STD. Could they just be swollen / burnt taste buds recurring or is it something else? And how can I help lessen the pain and heal them?
