I just became aware of a therapy called vsel. Dr Greenberg Bryn Mawr PA is an orthopedic doctor. Look it up. Technology is only 3 years old and is being practiced nationwide by other doctors as well. It is expensive and not covered by insurance. Blood is taken and your own embryonic stem cells are harvested. After going through some type of lazer technology the cells are put back into your body. I'm told results are amazing. If you go on dr Greenberg's website you can read about it. Good luck.
