I have dealt with chronic pain the last eight months sense rupturing a disc in my lower back...the "jelly" inside the disc leaked out into all the nerves running down into my leg.
I found a lot of success with spinal injections...I have had two. The second one took almost three weeks to help though and I was really thinking surgery was going to be in my future.
Then I found my massage therapist...I see her once a week for an hour massage...and it isn't the for fun and relaxation type...but she gets my back put back together. Two hours after my first session all the feeling came back into my leg. It had been numb sense the injury from my knee to my toes. I am usually pain free for about three to four days after seeing her.
My pain management doctor tried me on several different medications for pain not narcotics...Cymbalta which I had heard great things about (I had an allergic reaction to it...total bummer!!)...Trazadone was great for sleep but not so much for the pain...he also offered several other options of anti-depressants that I declined due to previous attempts on them and side effects. But many of them really really help with nerve pain...I am just very sensitive to them the SSRIs.
Find a pain management doctor and go from there...mine is open to anything that will help, spinal injections, medication (non-narcotic), massage, acupuncture, etc. They might even have a cash discount if money is a problem and the drug companies offer low or no payment medications if you find one that works and need help paying for it.
Sending you a hug...no one really gets chronic pain until you have lived with it!!
