Hi! i am a 31 yr old female who has had tonsilitis since i was 1yrs old, in 2002 my doctor noticed i had a swelling in the back of my throat and i was later diagnosed with sinusitis, in 2009 i had a tonsilectomy done but i still suffer from a headache on the right side of my head, congestion, a swollen lymph node on that side which i feel when i swallow and severe neck pain. this problem comes and goes. please help me with an idea of what is causing this
