I have what looks like a cyst on the palm of my right hand. It's about an inch below my ring finger. Sometimes when I wake up in the morning, my thumb and the first three fingers are numb and tingly. I flex my hand to get the circulation started, but most times it gets really painful before it gets better. And sometimes the pain goes all the way up my arm to my armpit. I am wondering if the cyst could be putting pressure on a nerve. I've had the cyst for about a month. Right now my fingertips on that hand are numb and tingly.
