Have had 3 steroidal injections L2-L3, 3 nerve blocks from l2-L5 and rhizotomy on left and right sides. pain down left leg, very tight muscles in upper leg with sharp pain at times in front of both legs. ROM is limited, am seeing PT at this time. Neurosurgeon wants to fuse L2, L3. a Would like to know if stem cell therapy is a possiblility, pros and cons, etc. Plus if viable treatment, risks, and where it is being done.
