Mostly at night while sleeping my right hand gets numb. Sometimes I feel like my hand is swollen and it hurts slightly. When I am awake the numbness goes away, but then suddenly it returns. Even if I am awake at times, just sitting or while having a shower, the numbness suddenly starts until I keep pressing my hand or running it under warm water. I also have spondylosis of my neck and when really stressed out I get sever pain on my left shoulder and full arm. But the numbness has never happended on my left hand only on my right hand palm only. Please help. Thanks
