@danny5 do you do any stretching exercises before you retire for bed? I had a similar issue but once I started doing my HEP (home exercise program) upon waking and at bedtime my issue stopped. I feel if I fatigue my muscles before I go to bed my muscle and nerves don’t need to fire without cause. For me it’s the same thing as exercising to relieve pain which is normal. Give it a try as it may work.
