Who ordered your MRI?
How long ago did you have an MRI
Have you seen a spine specialist?
If you have not seen a spine specialist, you need to be evaluated by one for a proper diagnosis.
You need to see either an orthopedic surgeon who specializes in spines or a neurosurgeon that specializes in spines only.
As for the MRI being negative, that is a very ambiguous statement. An MRI is only a small tool in the larger picture of diagnosing a spinal problem and spinal pain.
What may appear to be normal on an MRI picture for one person, can create havoc in another person's spine.
A good doctor will use the MRI pics as a tool in helping to diagnose a patient and just say "the MRI is negative" and you still have pain.
That is why it is so important to see a good spinal specialist.
If you have been seeing a spinal specialist, then you need to get a second opinion.
Good luck
