I have ganglion cysts on the inside of both wrists, on the outside of my forearms (around the widest part) and on the outside of my wrists, a little ways back from my wristbone. None of my ganglion thingies are actually on a joint - they're usually a couple of inches away.
Yes, now that I googled images, I'm pretty sure that's what it must be! So, this is not a drop-everything-and-get-to-the-doctor situation, which is nice since I've gone enough for other reasons. I'll look more into the causes and treatments, I guess it is just a weird coincidence!
Yes this just might be a ganglion cyst. My daughter has one and it is nothing to worry about unless it causes pain or gets large and touches nerves,,, which causes pain. other then that nothing to worry about
However If I was you i'd show my PCP at the next visit just to make sure. Uno what I mean? when do you see your doc again? I also think like you that you dont need to go to the ER. But get it checked out ok?
If this appeared suddenly, it is far and away most likely a ganglion cyst. They do arise in the joint , but may show up under the tendon sheath along a finger. No, this is not an ER kind of thing. Tell your doc next visit. If it keeps you from full use of your hand be seen earlier. Treatments include letting them be, injecting them with steroids, and surfgical removal, but they can always return.
Old home remedy was to hit them hard with the Bible which would suddenly pop them, or, alternatively, to put the fear of God into them.
Heh... They don't recommend that now, I guess because there might be fluid in them which would cause a problem if it got into your system.
I've tried to get hubby to whack me with the phonebook, but he just can't hit his wife! ;-)
