I had a bad canker sore at my lip section that lasted 2 weeks (now healing since I went to the doctor) which started by me accidentally biting on it while eating. After a few days a big canker sore then appeared at my left throat. I thought it was sore throat so since the pain prevents me to sleep already, I went to the doctor and he did some procedure to lessen the pain (he kinda burned the pus I guess) along with my lip canker sore. Both are now healing but now I am freaking out because I just discovered two bumps left and right at the back of my tongue. Both are painless, about a lil less than a centimeter in diameter. It's kinda big compared to the regular ol bumps I would get from time to time on my tongue. I'm really freaking out since it might be a sign of an infection related to hiv. Should I be concerned at this point? I'm also freaking out because I might have mouth cancer. My father side has a history of cancer.
