Have had 2 done trying to relieve severe leg and feet pain and tightness..seems to help a little. Is it worth the risk or is there a risk? I am willing to do just about anything at this point..walking is becoming next to impossible! Losing my balance, weakness, severe pain and tightness in left leg and ankle, both feet are completely numb. I am fused from L1 to S1..I am done with surgeries.
