The fact that the side effect is not common does not mean that
what you feel
is not related to the medication. I cannot really say if the medication
is causing you the problem or not. However if you feel that your neuropathy worsens with the medication, specially after doing the trial of going off the medication and seeing the symptoms improve, I think you should discuss this issue with your doctor, and consider changing the treatment.
I hope you find this information useful.
