Hi John and @bonnieh218 ~
I've been scanning the Mayo connect tonight and looking at my past posts, etc.. I saw this and decided I can contribute because I just had a diagnosis last week of a cyst on my left hand middle finger which is just below the nail and cuticle . I had been noticing it as a depression at first and it looked also like the skin was shiny, and it was like the skn is irritated there and just not right... So I think this was many many months ago. My recollection isn't good on this but okay, so I have some ointment for when I get any open spot for me to put on to avoid infections. It's called Mupirocin. My dermatologist is the Dr who I showed it to and he said it is a cyst. I don't recall the name of it though. But he did use a type of syringe to extract the clear gel that was in it. Then he put some kind of steroid in it to help. He wants to recheck in a month..then after another couple times of extracting the gel, he says he will be referring me to a HAND surgeon. John, its not a gangleon cyst, the dermatologist told me this when I asked about my finger. But i cant remember what he called it...However, I did have a Gangleon cyst on my right wrist that got so large I had to have it removed by a hand surgeon and that was in 2003. That was not ever conveyed to me at all that either one was related to the Osteoarthritis in my hands. At the time of the wrist cyst I hadn't been diagnosed yet with osteoarthritis. So.the Hand Surgeon just told me that some people get them and are prone to cysts more than others. Gangleon cysts are not malignant and are also filled with a clear gel just like this one I have on myfinger now. Hope that you get some help. If you find out more about this finger cyst then please post it here Thanks.

Good information, thank you for sharing @darlia!

I have a mucous cyst on my finger near my last joint. It is not near the fingernail at all. The cyst just pops on its own when it gets to a larger size, I've never had it popped by anyone. The clear gel drains out and I am left with raw skin where I put a little Neosporin on it and a Band-Aid for a couple days. Then the cyst starts growing again and the process repeats itself. Last month, after the cyst had popped and drained on its own, I started using Dr. Teals Lotion with Epson salts in it on my hands for my osteoporosis. This last week I noticed my cyst is gone and hasn't started regrowing at all. Going to keep up with this lotion and closely follow whatever happens with this cyst. Maybe this might be of some help to you. All the best!
