daniella,
What ever you do I pray that you find some piece of mind and pain relief. About a year ago I was on some boards asking people who had lost their feet and legs if they suffered a great amount of pain as I was considering having my right foot amputated to get relief from pain. I still have it and can move around with a cane. I change my medication to add methadone to my Lyrica and found some relief 3-4 range plus being able to get some decent rest at night. good Luck to you and everyone else.
