Nicole, is your pain in your hamstring? I am assuming you did not have surgery in that area. I was getting pain in my hamstring, but it was a muscle spams – like a pulled muscle. The nerve pain that I have is the area wear my leg is numb. The OS also told me that the numbness will take a while to reside.
Try icing that area and see if that relieves the pain when you bend your knee (could be your sciatica) I find icing my thigh and back helps with some discomfort.
