6,000mg of aspirin a day?! I thought anything over like 3,000 was borderline dangerous for organs, especially your liver.
I thought fentanyl was the most effective painkiller?
Either way dude, get addicted to percocet or something, I'd talk to my doctor about getting something for localized numbness, and I'd go soon while you still have freezer burn on your leg to help convince the amount of agony you were in and what you were willing to go through. If he doesn't help, steal a script book!
Edit: Oh, by the way, ice works well to bring down swelling.
Try 15 min on, 10 min off, 15 on, 10 min off though, not 8 hours on.
