OK, yeah, getting a handjob might release some endorphins and make you feel better temporarily, but it isn’t going get the knots out of your muscles that are causing the problem.
I recommend looking for a good, nationally certified and licensed massage therapist instead.
Now, in my experience, (chronic back pain, at times it has been close to crippling), M.D.'s simply are useless. Go to a doctor, who barely even looks at my back, prescribes muscle relaxants and pain meds that do nothing to relax the muscles or relieve the pain. Go to another doctor, who barely looks at my back, prescribes different muscle relaxants and pain meds which do nothing to relieve the pain. Go back, get sent for X-rays, hobble into the hospital X-ray lab, crawl onto the table, get pictures taken, hobble home, get a call a few days later saying that the X-rays show no abnormalities, go back to the doctor (or to a different one), who barely looks at my back, prescribes muscle relaxants and pain meds that do nothing to help the pain…
Repeat for months on end
Finally get a referral from a friend to a good chiropractor, who actually (gasp) examines my back, puts me on the rack and cracks and crunches my spine, I get a good deal of pain relief, and after a couple more adjustments I’m virtually pain free for weeks or even months.
See, there’s no “scientific evidence” that chiropractic, among other alternative therapies, works. But there are lot of people like me wandering around out here in the real world who have gotten real benefits after the “scientifically verifiable” medical treatments have failed repeatedly.
