Sure it's not a ganglion cyst CBS? Very odd to get DC without having a male on your side of the family (dad, granddad) with it. If it is, avoid surgery (although many need it) because it is recurrent, and the more times you get surgery, the harder it is to get in there. Basically by the 3rd surgery it's a friggin mess in there and you're stuck. Same goes with steroid injections. Yes, the 1st one may wipe it out, but after a few, you've totally f'd up you hand and it's not worth the penalty.
Stretch it, aggresively (i.e. by someone else than you) massge it, heat it, parafin bath, do research. nip it in the bud.
