My boss had a hip replacement and I was amazed at his mobility within two months. I on the other hand had foot surgery and was in extreme pain due to nerve damage which the surgeon could not explain and did little about. Demanding better treatment I was refered to a pain clinic. From there with additional pressure from me I was finally seen by a neurologist. Save yourself the months or years of pain with one sentence to the doc - "Treat the pain or find someone who will." There is nothing unreasonable about that request. Maybe your recovery time is extended, but I was told that much of my suffering was unnecessary, caused by the original doc not knowing, not caring or both and also harder to treat because of of the lack of timely attention.
