I had a discectomy (L5-S1) in 2002 and a fusion & laminectomy (L4-5) in 2007. I've recently been diagnosed with 2 DVTs (Deep Vein Thrombosis) in my right thigh. I've had other problems with that leg before and after surgery. It's less flexible compared to my left and I'v had problems with my hamstring. Naturally, I favor my right leg since that seems to give me more problems. My question is... are the DVTs a direct result from my back problems or is it purely coincidental?
