Maybe someone can help me understand some things about MS. I am having a problem with tightness in my calf muscles, feels like it may go into a cramp at any minute but it doesn't, it can last for a few hours or a day and then go away. The Nurse Practitioner did not think it was related to MS back in Dec. when I had this problem, but my low Vit D so I took Vit D and now I am at normal and the tightness is back. Any ideas?

Please fogive me,I'm still trying to figure out this website and how to use it. I keep trying to change my profile because I did not fill everything out and now it won't let me fix it. Oh well!:
