nasty taste in my mouth and bumps on tongue

I got sick like a week ago and I have had this nasty taste in my mouth and my tongue has been feeling weird. I went to the doctor and he said I was sick and was going to give me a prescription for amoxicillin. Then he looked in my mouth again and asked if my tongue hurt and I said no. Now the next day I looked at my tongue and there are similar bumps they are part of my tongue, but they are sticking up and they feel funny and there are bigger bumps on the back of my tongue. They don't hurt, but are bigger and don't look like the other bumps.
