I have a different answer for you.
More than likely, if this is a disc problem it is chronic disc degenration in the early stages.
A herniated disc typically would cause acute pain and a radiculopathy...pain radiating to one arm, or the other, or both.
I have never see a recurrent disc problem that goes away on its own and then comes back.
You need to see a physical medicine and rehabilitation doctor or orthopedist and have an exam before having your doctor order an MRI.
This will allow an exam based focus on correct levels, and save money.
Degenerative disc disease can be arrested with the correct manual medicine program, which I can go over with you if you like.
To answer your other question which has not been addressed, 99 is not a fever.
It is not really even a temperature.
If this is happening frequently, hyperthyrodism and other problems would need to be ruled out.
OK, so that is an initial answer….
