its been 9 months since I was misdiagnosed w/what turned out to be shingles in my sciatic nerve,resulting in pain,numbness,i had 2 falls,resulting in a herniated disc.My quadricep was affected and I have difficulty walking ,if not assisted,further than a short distance.My leg is extremely tight,and still numb.Besides physical therapy,is there anything that might help w/either the numbness or tightness?
