Brief Answer:
Ganglion cyst.

Detailed Answer:
Hello.

Thank you for the query.

Can you please attach a photo of it?
From your description most probable explanation is a ganglion cyst.
Its a benign lesion connected with a tendon and filled with clear fluid. It does NOT turn into a cancer.
It can be removed if causes pain.
Ultrasound can confirm it.

Hope this helps.
Regards.

Hello, six months ago I had a ganglia cyst removed from my inner wrist.I woke that night in severe pain as i scratched my back in my sleep ,it hurt so bad i nearly passed out and vomited.I was on pain killers for a month,when I saw my doctor again, he suggested opening it up to have a look,he gave me antidepressants and sent me on my way.. I am in constant pain,its not right. please advise me on what my options are.I think he has damaged my nerves in my skin, it hurts like sore pins and needles, and long stretch movements hurt alot,. I have endured alot of pain.Im scared now too cause my other wrist is sore,but its a lump on the upper side of my wrist. I need help now, but i dont trust my local doctor anymore. He gave me no warning of the damage that could have happened,also no options. Im a mother of four young children please advise me.
