my son has a lump on the back of his hand, when the doctor drains it the fluid is yellowish.  Still dont have a diagnosis for the lump. what couls this be, and why does it keep coming back.  came back within 4 hours after it was drained the last time. HELP!!!
Hi, It is very difficult to diagnose a lump without examination. But the way you described to me, it seems to be Ganglionic cyst. There are high chance of recurrence if you just Chat Doctor. Ideal treatment for ganglion would be excision. Thanks
