question: Hi, I have a lump on the back of my hand, located in my wrist that seems to fluctuate according to weather conditions.  It is very painful when it appears and affects the movement in my hand.  It tends to appear for several days at a time.  I have experienced the same in the other wrist too but not always at the same time.  I also experience pain and swelling in some of my fingers from time to time.   Do you have any idea what this may be please.
