I am a 25 year old female who had had constant arm pain ONLY when lying down or reclining. If the pain comes while lying down within 1 minute of sitting it goes away. This has been occuring for 7 years now. I have been to doctors about it and done everything from massage therepy to and EMG which revealed nothing. It comes and goes with how severe the pain is. One month it will be moderate and the next month I will be sitting in bed crying. It radiates all the way down my left arm, but is most prominate in my shoulder and upper arm. When my husband will massage my arm it will relieve the pain for a little while. I just have NO idea what it could be. if I am sitting or standing there is no pain at all. And the doctors are stumped. Any ideas??
