After tonsillitis.....achy squeezy glands in head and dizzy

[IndigoBarbie]

I'm recovering after being in bed/antibiotics with tonsillitis, thing is though - I am dizzy and I keep taking these 'moments' of what I've been told are glands at the base of my skull - but more behind the ears - when they get all vice like grippy, and the feeling of dizzyness and fuzziness is intermittant during the day.
Has anyone else had this symptom? I feel more spaced out than ever. My antibiotics are finished a few days ago, but I feel extremely tired....
