I keep getting a butterflies sensation in my stomach then straight after, my arms or Legs sometimes both, sort of spasm and jerk. It generally happens when I am lying down and can go on like a repetitive loop for quite a long time. I have a long illness diagnosis of M.E and also have generalised arthritis and a bad back. I find that generally I if I am standing up the maximum time I can actually stand without being in extreme pain in my back is less than a minute. The flip side is, that unless it is my rise and recline armchair that I sit in, after about 45 - 60 seconds I have to stand up because of the extreme pain in the knees and more so in the right hip. I am sure people think I am just lazy, but I can assure you I'm not, but living with this day in and day out is exhausting and demoralising. Even visiting the doctor is avoided as I don't believe he thinks I am in such a poor state of both physical health as well as the psychological effect of dealing with problems I experience and find demoralising. Any advice anyone?
