I am a 47 year old female. The last couple of weeks I ve been experiencing significant pain that seems to increase with inactivity. Its sharp stabbing pain in my fingers, arms, hips, feet, hips and shins. I do experience the pain throughout the day with activity but as soon as i sit or lie down there is substantial increase in the pain level. I was diagnosed with MS in May 2006, but this is an entirely new and different pain than i have ever had.
