Red Bumps On Back of Tongue And Throat

For the past three days my tongue has looked a little white. I used the tongue scrapper and flossed. Today I was reading information on the internet. I look at the very back of my tongue and notice that I have red bumps. Also, on the back of my throat I have a few red bumps as well. I haven`t felt any pain. I was just looking and found them but the back of my throat felt dry the past 3 days. Is this a symptom of HIV?
