Yeah Olly, the spasticity was my first symptom in my legs years ago. So that's what I always figure the pain is from (it's not just pain in the joints), like I said it's a long gap in time of taking the medication. I never assumed I had or have Arthritis. But it does make you wonder about the toll that pls takes on someone's joints. I mean my gait is way different, with my leg swinging out, feet turning in, knees hurting...I just wonder about the long term related side effects.
