I have tried all of the above and use them. Sometimes I wonder why I continue to use them since they don't work but I keep after it. I've lost count of how many injections I've received over the last few years. I cannot find a doctor to prescribe anything for pain although I do get Baclofen for muscle spasms. They will prescribe other medications like an antidepressant, Neurontin, Lyrica, etc. but they have all given me terrible side effects from migraines to vertigo. I just don't tolerate many medications. I did use Tramadol for a bit. It was enough to take the edge off and get me through my work day but when they wouldn't renew that, I had to quit my job. I think the CDC and Joint Commission has intimidated the medical community over pain medications, to the point that it has had a negative impact on patients.
