Thank you. I do not want to get too personal on this public forum, so only answer if you are comfortable. Did you have stem cell due to a fracture of the hip from OP? Did they put stem cells at area of the surgery or more as a general hopeful boost to the blood stream. Was this at a "Regenexx " clinic, who seem to do more orthopedic/sports? If you wish to comment, please do. If not on this site, I can send you my email. Again, I appreciate your comments and if not comfortable, no worries.
