My finger has a hard knot on it and I can press and rub on it and it will soften up but it will not go away. It just throbs. What can it be. I have tried to stick a pin in it and drain it, but it nothing ever comes out

Brief Answer: hi and welcome to hcm Detailed Answer: Thanks for the query. I d like to see photo of it but it sounds like ganglion cyst which is common in this finger area and it is fluid filled cyst made of fibrous capsule. Other possible causes are fibroma,lipoma or ateroma. In every case it can be surgically removed under local anasthesia and it rarely disappear spontaneously. You should not pin it or do removal by yourself. Wish you good health.feel free to ask. Regards

Brief Answer: hi Detailed Answer: As I can see this is swelling of proximall iterphalangeal joint and there is slight redness around it so it indicates inflammation. It can be part of any type of arhritis or inflamation of joint bursa. so you should do Xrays to rule this out. Also,take nonsteroid antiinflamamtory medicines,rest, and put ice compresses on it. If swelling progresses,then surgical drainage and immobilisation may be necessary.
