I had a bicusp pulled on the lower left side, because my tooth broke in half, and it was hurting, the dentist pulled it 5 days later, and now I'm in more pain, and i have a pea size not inside my mouth on my gums by where the tooth was pulled, and also my lymph node is swolen on the left side just below my ear on my neck, about the size of a quarter, they have put me on penicillian vk 500 mg every six hours, and oxycodone 5mg/325. I can not eat, I'm in so much pain, i can't sleep, and if my face tilts foward just a little bit, i have pressure. what should I do. I need help now
