Mike,
Get the MRI done, you may have more than just a pinched nerve. Went down this road when I fell at work in 1989 and ended up with paralysis in the Rt leg for 10 years. I was hard headed and fought surgery. turned out I had a spinal compression that ruptured at L4-L4 and L5-S1. Two laminectomies and a 2 level PLIF to get the pain abated and the rt leg back. so many complications form all of this and a general decline in my health until 2010. Get this checked, please.

Bill
