I've been slowly adjusting my dosage of Tizanidine the past few weeks. I'm learning that I need a certain amount of spasticity. When I went up to 8 mg / day, my knees were very unstable and painful. Now I'm taking 2mg in the morning and 2mg more at night. Knee pain is basically gone, except my dr found a spur under my kneecap. He gave me a Rx for Tramadol for knee pain. I am back to walking on my treadmill (not going nuts with it) because all the laying around was making my back hurt. Legs feel heavy but not painful. This seems like a never ending ordeal and I'm only at 5 months. Don't know how you do it. I want a diagnosis but maybe it's better that I'm confusing them!
