the tight band is also part of the issue. If you have any questions about the doctor, go with your gut. Was this surgery done at a major medical center? Most drs. will tell you that if the surgery was less than a year they don't want to do much. It can take up to two years for everything to "fall into place." I don't understand why you are having a bone scan and not an xray or MRI.
Is there swelling? Hurt more when going up and down steps?
