I went to a surgeon after exausting all other options open to me, and the simply agonizing pain woke me at night and showed no signs of abating.
He operated on one hand, then, after about a month, on the other. The surgery itself was without incident, and the recovery was uneventful, too.
The downside is that my 'iron' grip is now only about 90% of what it was (an estimate), which makes little practical difference, except in opening the most obdurate lids(!). And, I had insurance to pay for it.
The important thing was that I have never suffered from the hellish pain that I experienced daily for several months--and I kept a surgeon gainfully employed, too!
So, I have returned to my hovel somewhat happier--and he returned to his mansion, somewhat richer. Who could ask for more?
Thanks, I suppose I should have researched it, but am glad you (both) have provided corrections. But this reveals an even more interesting story waiting to be told...
