Doctor's Visit - Still Looking for Answers

I went to see an orthopedic specialist today about the ongoing pain in my foot.  The nurse took some xrays and I discussed the problem with the doctor.  I ended up leaving his office in an ankle brace.  He was not able to determine what may be causing the problem but had a couple of ideas.  The next step in the process is to have a bone scan done at a medical facility and follow up with the orthopedic specialist in a week.  So at this point I am basically where I was when I started this process.  I keep trying and trying but I am unable to find out what is causing the pain and more importantly what can be done to get rid of it.
