Had MS since 2014 and my symptoms are spasms in the back on both side and trigeminal neurolog (tn). Does any one have the back spasms? Right side approx 80% of the time with 4 to6 intensity. Left side 30% with intensity of 7 to 9. Left side feels like a tearing burning sensation. Most movement causes one or the other. Don't know what to do. Very hard to sleep. Anyone experience this?
