What is wrong with my wisdom tooth extract? Sharp pain after a week!?

I got my impacted, lower, right wisdom tooth removed last Saturday. Today is Monday and I am still in pain. I think i may have a dry socket but I am not sure. On the day of, I was spitting constantly because my throat was super sore and I was bleeding profusely and did not want to swallow it. My dentist gave me very poor Post-Op instructions it wasn't until I did research that I knew i wasn't supposed to spit. I also ate on the way home from the dentist. I was ignorant to how serious my procedure had been. I wasn't given any antibiotics but I was put on percocet. I didn't take any days off from work but I did reduce to only eating non chewable foods. On Wednesday not only was I still in pain, my pills ran out. I called my dentist because everyone was saying that I should be better by now. He says that my case was severe and my tooth was right on the nerve and that i should be in pain and if I don't get better in 3 weeks then I should come in. He gave me antibiotics and 600mg Motrin. I have been putting clove oil to help deal with the pain, I do rinse my mouth with salt water twice a day after brushing. Today is Monday, a week and 2 days after surgery and I am just sick of the pain. My pain isn't exactly on the extraction site its more along my jaw bone and surrounding teeth. Should I listen to the dentist and wait? What could possibly be wrong? Normally, I would just get a second opinion but I don't longer have health insurance so I need to do at home treatments since I paid for the extraction out of pocket. HELP!
