A pain management specialist is not the first doctor to go to.
And they are not for temporary relieve.
They are for long term pain management.
As I said, at least in the US, the PM&R doctor is THE specialist in physical medicine.
You did not state that an MRI was ordered, and as I first recommended, this would be definitive along with an EMG/NCS .
In fact, a neurologist is not indicated for a structural problem, and is not going to see you without a referral for a neurological problem.
That is basically how the system works, and would be an initial waste of your time if this is not strictly a neurological problem.
Spinal problems with discs are typically handled by a spinal orthopedist or a PM&R doctor.
This is the original expert. I am a double board certified US doctor.
Find me by request in medical any time. For Dr. Thomas only.
