Myositis on the other hand is inflammation within and throughout the muscles. If not treated properly it can lead to atrophy and muscle weakness that is irreversible. Of course treatment for any Myositis disease is difficult. My hands had swollen so much that we almost had to cut off my wedding ring. I no longer wear jewelry, because that symptom occurs every day.
Nothing really triggers it, it just happens.
I ve had the same experience while driving as well. My arms will begin to ache and feel heavy, and then my hands become numb. I took my daughter out of school early one Friday just in case I couldn t make the round trip. We were there for only two hours. All day Saturday I was in bed wrenching with the pain from attending that meet.
