If you haven't tried TENS, I highly recommend it. You can find them on Amazon or eBay for less than $50. The key to using Tens successfully is to place the transducer pads over a nerve that feeds the problem area with the problem area between the two nerves. Step up the current until you readily feel it and then step down one setting. Using the device with high current isn't necessary to get relief and will cause muscle pain if done often (the pulses create muscle contraction and you don't want much of that. They are portable with wireless remote controls. So, you can put them to work under your clothes and go about your business. Also, you can Google for Acupuncture/Acupressure charts showing nerve points; if you don't feel the current on a low setting, experiment by moving the transducer to a different spot. There is a wealth of info to be found on Google for how to use them. Many nights I would get no sleep if I didn't have mine next to the bed available for use. My PN is sort of weird, some nights it doesn't bother me at all, and other times it is hell on earth.
