Painful white bumps on tongue

I got a very painful sore on my inner lower lip and the doctor said it was probably a cankor sore. Within 4 days I got these painful white bumps on my tongue that are almost pus filled. They are all over my upper front tongue and are multiplying. It hurts to have anything cold or hot. I think they are contagious. The sore on inner lip is almost healed but the more that heals the more the bumps/spots on my tongue multiply. I've also been dealing with these sores I get on my body that also have a white root-like core to them and take months to heal. I was told years ago that I have autoimmunity disease and wonder if this is a specific one. I had CBC done and my white blood cell count is high. I've been on multiple antibiotics over the last 3 months but none have helped. I also had a bad staph infection and am concerned the antibiotics did not cure that and it is in my bloodstream but I don't know if that would show up in the mouth like that. I have been very very clean, brushing, rinsing, antibacterial soaps, etc. Please help!
