Back of my throat hurts and I feel as if it is shrinking and swelling, I have taken antibiotics it feels as if it is getting better, as soon as the course finishes the swelling comes back, I am know taking paracetamol two tablets twice a day as soon as the medication wears off it comes back I also feel as if I am getting a high temperature if I don't take this. If have been to hospital and had a camera put through my nose to check my throat but they could not see any thing, please help what should I do.
