I do have a TENS unit. No help. Physical therapy utilized core exercises. No help. Tried a chiropractor yrs ago when the pain was less, no help. Have not tried massage therapy or acupuncture yet. I have stenosis. I do not think massage will help that. I need a med that works on the pain messages to the brain. I have no faith in acupuncture, but maybe I'll give it a try. I'll see if my ins covers it.
I've tried acupuncture; temporary relief, and honestly, I think it's mostly psychosomatic.
I also have spinal stenosis. The only medications that work for me are opioids. My Dr tried me on a class of meds called inhibitors, that cut off your brain receptor's ability to perceive or transmit pain, but they don't work on the type of pain stenosis causes. Plus they made me feel drunk and stupid all the time.
I've had 3 RFA procedures; 2 worked, one didn't. One of the ones that worked, the 1st one, kept me gloriously pain free for 6 months, and relatively pain free another 3 months. The second one did the same but for less time, a total of about 5 months.
Physical therapy doesn't do a thing, but hanging head-down helps for hours. I do this at home: hang by my knees from a padded chin bar with my shoulders just about an inch from the floor, and my head rests on the floor. This decompresses your spine, and you feel really good for, like I say, a few hours or so. A large slant board works, too, if you lie on it on your back with your head at the low end, but
inversion tables work even better (at a 45 to 80-degree angle). And you can do this every day and multiple times a day if you want. You only have to do it for 10-15 minutes.
