I have myself spasm's in my legs and have been taken zanaflex 4mg for years now my doctor changed me to valum and I felt like my head was separateing one part felt weird and the middle felt dead and I thought I might be going to have a stroke so I had about 15 left and. Now I don't have anymore and have been taken the 5mg valum do you think I will get that weird felling again? And I've got to go to doctor in too weeks and was wondering if it would be out of my system buy then?
