[|Human|] I have  a hard knot that has come upon my wrist over the past few months.  It is on the top of the wrist on the left hand.  When the hand is straight it does not show as much.  When the hand is bent downward it pops up like a bubble.   Could it be related to carpal tunnel?  Or something else...
[|AI|]  Hi, The most common problem leading to a hard knot over the back of the wrist is either a carpal boss, which is a hard swelling which forms at the junction of the wrist and hand bones. It is mainly related to common wear and tear processes occurring in the joint and very occasionally leads to any problems. Another possibility is a ganglion, which is an out pouching of extra lubricant fluid around the tendons crossing the wrist that can appear like this. It can be a cause of carpal tunnel, which is when it would be requiring surgery. But only if you have symptoms of carpal tunnel syn Chat Doctor. So my suggestion would be to leave it unless it is causing pain or loss of function. Cosmetic problem alone is not enough to warrant removal. Thank you.
