Back/leg pain, foot drop\toes tingle.mri inconclusive for disc cause.ref to neuro for testing.3rd relapse, could ms be a cause of symptoms?

Drop foot: Ms is not the only cause of a drop foot deformity. Muscle weakness is possibly from nerve damage which has many causes. You should research other symptoms of ms and the testing/treatments and talk to neurologist about any symptoms you have to help diagnose/ resolve problems. Consider other more urgent causes such as stroke or cva.

Foot drop: I agree - speak to your neurologist frankly and discuss your concerns. Good luck.
