I have pad and a diabetic foot ulcer, i have been taking percocet 10mg/325 but it does not relieve the pain very long, what type of pain medication and how many mg will help me stay pain free through the day?

Nothing: You need to get the blood vessels open and circulating blood to the areas that are lacking blood and are anoxic and ulcerated. Try nattokinase 3 pills 2 times a day taken on an empty stomach . See a doctor who does chelation therapy to clear the toxins in your body and restore circulation. Then the pain may go away without the narcotics.

Need further workup: The Percocet will not fix the problem, it just masks the pain. First, you need a full workup to make sure you do not have an underlying infection (maybe even of the bone). If the pain is coming from infection, then antibiotics will help resolve the pain. Second, you need a thorough work up of your circulation to make sure it is adequate, if not vascular intervention may resolve the pain.

Serious problem: You have a serious problem my friend. It is bad enough to have diabetes with a foot ulcer. And now you have pad. That pain you feel is from the pad. There may be no amount of pain medication that will relieve your pain. The pain is from a lack of oxygen to your foot. This needs to be evaluated and perhaps corrected asap by a vascular surgeon. It will help the pain and help you heal.
