Are Red Bumps At The Throat A Symptom Of STD?

Hello, I have had these bumps on the very back of my throat for a little while now, almost a week. One has little red dots on it but the rest are a sorta flesh colored. They go down my throat and they vary in size. I did have a slight fever at the beging of the week and some aches and chills. I went to the dr. And tested negative for mono and strep, she gave me meds for strep anyway. I was raped 3 years ago and got tested for STDs 2 months later and it was negative. I have not had any other signs of sickness, just the bumps. There is some flemmy stuff back there, and sometimes I do get dry throat. Thank you, Hannah
