Does the spasms and cramping in your feet ever go away? Also does it end up making foot drop worse?
Have your doctor check your potassium level. Potassium is sometimes lacking when muscles cramp. You have to be careful not to take too much because it can be toxic. It helped with my spasticity and, as a side benefit, after I started taking one supplement a day when it was found to be low, I started sleeping better.
I think that exercise can help to reduce the spasms and cramping. Muscle relaxers help as well but no, nothing will cure it. Especially if this is your baseline. The baseline as I understand it is the severity and type of symptoms that you have when you aren't having a flare-up.
Always believe that things can get better and go away. I do not mean MS will be cured but you can get relief from spasms and pain. I had them in my legs and feet and it went away and has not return for 29 years.
I had horrible spasms in my legs but with physio and building control of my muscles (@exercise and stretching-everyday), I have no more spasms.I was tested on Thursday past, physio saw none.
When I was in the hospital, I had pain and muscle cramps, they check my Potassium level and it was low. The Doctors put me on potassium for a few days and all improved.
