I second JT's observation. Pool therapy helps me more than anything. Also consider getting massages. The other recommendations are likewise valid. None of which makes your legs feel better, but they are a good starting point. Oh, one last observation, consider marijuana. I like tinctures.

Often the nerve damage causes neuropathy....there is medication for it but I never tolerated it well. Exercise and antinflammatotry diet helps me. Swimming and water aerobics.

Yes, what is with the legs? OMG, any position hurts, there’s so much heaviness. Arrrgh! Arrgh! Thanks for the suggestions and strength to all ❤️💞🦾

Get it checked out with your neurologist, it could be MS, restless legs or anything.

If negative that gives you a baseline for future tests. It does not always show first time. I failed EMG for both legs/feet and arms/ hands...poly neuropathy. There is also a skin test for small motor neuropathy.
I have largely sensory deficits until I was 50.
