throat and tonsil infection

i have had awful problums with my throats over the years but lately i got 1 tonsil taken out had to stop operation over bled too much... long story short after the operation i smoke when i go out for a few pints and only smoke when i go out.
over a month and a half ago i was out and the 2 days later my neck blew out where the tonsil was taken out was like the glands got infected got augmention tablets for infection they worked a week later i went out and smoked again the other side of my throat glands swollen out again like any ideas??? went to the doctor i am on calvepen 666mg tablets since i started taken them i feel awful head ackes and just wrecked dont wanna do anything have 4 and a half days left to take got given 10 day course to clear if something was there seems like i am not getting better :(

Any Ideas Would Be Greatful
