I’m not a doctor, just speaking from experience. Try to get some muscle relaxants and pain medications from your doctor. They won’t cure, only help ease the pain.
Don’t sit for long periods of time without getting up and walking. I do this every 20 minutes. You don’t have to get up for long, just a couple of minutes and walk around a bit. This helps the nerves not be so irritated for me. You may want to get a gel cushion, or something that feels comfortable to you, to sit on at work and home.
You can also try espom salts in a warm tub for twenty minutes. Epsom salts are inexpensive and found at many grocery stores and most drug stores.
You can try trigger point injections, usually done with cortisone. They help relieve the inflammation.
I’ve not found a cure. Sometimes it will settle down for months, then start up again. Not sitting for long periods of time and the injections help me the most.
I’m waiting for even more improvements in technology before I try any type of surgery. They’re always getting better at these things. Good luck, I hope you can find what works for you.
