Piriformis syndrome is a thing with hips. The Piriformis is the long muscle that goes from the glutes down to the knees. I like the stretches by Dr Jo online, but it is better to get to PT for other weakened areas. I've had to periodically go to PT over the years and I really like the Osteopathic PTs best--they give me a program of stretches for the causal areas as well as the current problematic one. I've read lately that estrogen loss is causal for hip issues, but not convinced. The Piriformis stretches can be done when there is misery, but if you have lumbar issues, then there are others. I keep the print outs and, in older age, I have to keep doing them. Six weeks of PT just increases my strength to the point where I can actually do them.
