Should I still be in this much pain?

I had my tonsils removed on Monday and I am STILL in excruciating pain. The first couple of days were okay and drinking milkshakes soothed my throat. On the 3rd day, everything i ate/drank (besides water) KILLED my throat. It is now day 5 and I thought I would start to feel better. I can't eat or drink anything other than water. I feel extremely weak. I just want all this pain to be gone. I take my medicine, hydrocodone, every 4 hours. My ears and jaw hurt as well. Btw, I had HUGE tonsils so the holes left in my mouth are probably larger than those of most people who get their tonsils removed; could this be why I'm still suffering so much? Also, should I have been perscribed an antibiotic? I feel like I should have, but I was just given the hydrocodone. PLEASE PLEASE HELP!
