the lymph node behind my ear about 2 inches at the base of my skull is swollen and hurting me.

i went to teh doc monday afternoon and he said i have an infected lymph node and gave me keflex for 7 days. i'm on day 2.5 of the meds and my infection has gone down some but not totally. it's become hard to the touch and hot to the touch. i can barely lay my head on my pillow because it hurts if anything pushes on the infected area.

i'm miserable. dr appointment monday. he wants to see me after i finish my antibiotics. do i need to give it more time for the antibitics to do it's thing before i worry? is this something more serious??

i haven't been sick, besides swimmers ear about 2 weeks ago.

help me!! i don't want to have a biopsy if i don't have to. have panic attacks when it comes to blood or needles.
