question: i'm sick. i've been sick for weeks. two weeks ago, i went to the doctor and they said i had a sinus infection. they perscribed amoxcillin and i took it until my perscription was done. but now, i've been continually sick... right now, my left side of my neck hurts bad and my hearing is funny in my left ear. plus, ill get occassionall really bad pains in my head, like a severe headache
