Hi I have a hard mass on the back of my right hand that I had removed like 5 years ago, a few months later they had to go back in to remove more any how the area has came back again now it appears to becoming more involved in my hand to the point it is more painful, my thumb and little finger hurt also and along with some overall hand swelling at times.I am 45 year old female in good health.I cant remember what they called but it was not a cancerous type issue.
