Hi, I had L5S1fusion with instrumentation on Jan2015. I had sciatic pain in both legs. More in the buttocks and hamstring in one leg and tingling,numbness in other. However nerve pain in ankles and feet as well. Several months after surgery the sharp pain in buttocks has left but other symptoms are increasing. I've got swelling in feet, bunions occurred right before surgery and since. Can't walk far or will flair up. Really as soon as I wake up I get symptoms. I am 49, was very ate tic. Still ideal body weight and people still ask if I work out. Because I'm tone. Doctor said I was a great candidate. Had the the surgery because I had spondylolisthesis and thought it would help. Now things are getting worse and feel helpless. Fusion looks great on X-rays:, ctscans and doctor as confused as me. Getting nerve test next. As anyone had anything simar. Sorry so long.
