When I first herniated a disc in my back my chiropractor told me no hamstring stretches. With a herniated disc if you raise your leg out straight this pulls the nerve taut (as I understand, it isn't elastic) and so if there's a disc bulge it will hurt.
Because of this I haven't done any straight-leg hamstring stretches at all. Last time I saw my chiropractor a few weeks ago again he said don't do it with straight leg, but bend the knee (so lie on back and put hands around the knee/shin and pull towards you).
I think my hamstrings have become really tight and need stretching. When I lie on my back and try raise my legs the knee inevitably bends and I can't raise it straight past about 40 degrees. I actually saw a GP who told me to do normal hamstring stretches with a towel behind the calf, but I don't know which advice to listen to.
What time of hamstring stretches are appropriate for this condition and won't worsen/aggravate the pain? Thank you
