Thank you for your question. I'm very sorry to hear about your situation.
Lets address your questions one at a time.
1. Do you have a lawsuit regarding your foot.
On its face, there appears to be a misdiagnosis by your surgeon as to the causes of the complications you are experiencing. A lawsuit would be based in the law of medical malpractice. In this type of lawsuit you would need to find an attorney who specializes in medical malpractice in New Hampshire to assess your case. A medical malpractice case is very expensive to assert, as most of the claim requires a doctor to testify on your behalf as to the negligence of your surgeon. This means you (or your attorney) have to hire the doctor to provide this testimony
, which is what costs a lot of money. As your claim appears to be one that has a misdiagnosis involved, your chances of finding a medical malpractice attorney to take your case and finance the expenses for you is better than average.
2. Do you have a right to proper pain management?
Pain management is like any other medication, it is given to the patient with the consent of the doctor. If your doctor is refusing to provide you with the level of pain management you feel you need, the best thing for you to do is to change doctors. I know that is easier said than done. However, the law does not provide you with any remedy which would force your current doctor to change his recommendation on pain management.
I hope this helps and I wish you the best.
