A bit more fluid aspiration mapping the back of my right hand/wrist, and watching surgery on ganglionic cysts on youtube, has lead me to two conclusions.

One: I can be harmlessly drained of a good 20-30 ml of synovial fluid every so often from the reservoirs that cover the space of a business card across the back of my lower right hand, which modestly reduces pain.

Two: I need a hand surgeon consult. There is *no* way I can manage this thing myself.

Usually such a cyst would grow in all directions, not primarily in the horizonal plane: this has delayed diagnosis. I think I know why, though. I'm on enough blood pressure meds to make a horse woozy, have been for years - and that includes diuretics. So it's been growing in pulses, quite literally, under the constant low pressure of the dermis, spreading like pancake batter.

Entangling with my finger flexors.

Oh, removal is going to be *fun*.

It seems to be running under the dorsal vein of the hand, too. Usually even the big cysts wind up one side or the other, and rarely reach too far up. But this one's had a while to grow asymptomatic, I suspect.

It *might* be related to the trigger finger affecting my middle digit on that hand, and the wrist movement pain and restristion of flexor movement. It all *fits*... even the inconclusive ultrasound.

Now I just need to book an appointment work will let me *leave* for... and then convince my doctor to refer me to a surgeon who's willing to listen to some failled engineering student who's way too keen on exploratory tissuesampling to solve his problems to waste time and funds on an MRI that'll probably *also* be inconclusive, or just put me under and open the damn thing up and take a video . 9.9

I'll need a good elevator pitch.
