Hi, my name is Bob, 72 years old and live in France, I had a stroke 4 months back and it has left me with a weak left arm with little use of my fingers. Physio was going well until I developed a swelling in my left hand that has caused muscle weakness and really inhibits normal physio exercises. During the day the swelling is not too bad, but at night when my arm is pretty much not moving, the swelling is quite severe and typically wakes me up after about 30 mins sleep. The pressure in my arm causes enough pain which is only relieved if I sit on the side of the bed for about 5 mins, after which I can lie down again and maybe snatch another half hours sleep. My doctor has given me some sleeping pills which work, but I find the longer I sleep, the greater is the swelling and the resultant pain when I awake. As a lay person, educated in this matter by the internet, it seems to me that Lymph fluid is forming and not draining while my arm is stationary. Algo dystrophy has been suggested and I am half way through a course of daily injections of calcitonin. No improvement has occurred to date. Is this a problem suffered by other folk out there?
