Hi . If your toes are going black, you need to get to an ER immediately. That is a very serious condition. It sounds like you are experiencing significant spasticity. There are medications and treatments that can help. Here is an article with more information: https://multiplesclerosis.net/symptoms/stiffness-involuntary-muscle-spasms. But please get to an ER right away. You might have caused some damage by using ice on your feet. Please keep us posted if you are comfortable doing so. I will be thinking of you and worrying about you. - Lori (Team Member)
