Hi, thanks! I did an exercise whereby you sit upright in a chair and point your toes on the affected side up while tipping your head back, then point toes down and put head downward. The sports massage therapist gave me that one, along with lying on my back leg up in hamstring stretch while using my fingers to push into the back of my thigh. I think those were both flossing techniques, it’s hard to say if they helped, maybe a little (because muscles seem to go into spasm with the nerve compression) loosening things off but underlying the problem was still there unfortunately.
