I hav a swelling on the back part of my palm close to the joint where your wrist is at times it swels and i can barely close my wrist.its like a lump ?

Ganglion cyst: Sounds like a ganglion cyst: a benign cyst that communicates with the wrist joint. These can be surgically removed but have a rather high rate of recurrence and sometimes disappear spontaneously. See a hand surgeon for a precise diagnosis.

See hand doctor: There are many orthopedic surgeons and many plastic surgeons specialize in treating the hand problems. You should not delay with your problem and should see one of them. Let him/her examine you and advise the treatment.
