I definitely think you should have a lumbar MRI. And PLEASE DO NOT go to a chiropractor ANYMORE. Anytime you have problems with your spine, according to my NEUROSURGEON, you could end up paralyzed and in a wheelchair if you're manipulated by a chiropractor!!! So no more chiro's okay???
After you have your MRI of the lumbar, bring the report here so we can see it, and we'll decipher it for you. Best of luck & God bless. Hugs, Lee
