You know what to do as do we all, when this happens: see a doctor. to learn what is actually wrong. Once you know what is wrong, you can begin to trace back to what is causing the pain.

Unless your driller is a physical therapist or trained in the science of your bones, tenons, ligaments and muscles, he can't truly help. All he can do is what many car mechanics do: suggest changes one by one until he and you luckily find a cure. You need more than luck here. You need to know what is actually hurting you.

It could be spans, it could be pitches or some combination. Since your driller screwed up to begin with (unless you are now doing something very wrong), I'd find another pro shop which is considered skilled in fitting hands to balls.

I had gradual growing wrist pain, used a brace for a while which helped, but ended up at Dr. turns out I had worn out the cartilage in my wrist, had a fusion surgery 5 months ago, back at it with no wrist pain, but grip strength is not all the way back (and might not get it all back)
Seek Professional help from a DR, not internet advice.....

I have a few customers that experience wrist pain when bowling.  I agree, seeing a doctor is the best solution but if you want to play with you grip try Bill Halls Tri-Grip.  This grip has worked for my customers and the pain has gone away. Again, seeing a doctor is the best advice but trying this grip may help.

but this solution is sheer luck that this devices addresses the problem.
If the op wishes to cast his dice with his future, so be it. The results rest on his head, no one else's.

I might add that you really should see a hand specialist, too.  Not all orthopedic surgeons specialize in everything.  The hand and wrist are remarkably complex and why leave anything else to chance?

True.

I see a different orthopedist for my ankle, for my foot, for my hip, for my hamstring, for my ass!!!!!! (no joke)

And my wife saw a different one for her back.
My back is not yet a problem: Strong back, weak mind.

Great advice on the specialist.
Got a lead from a local Physical Therapist who said he was the best around
He worked on a few NBA guys in town, so that was good
He was straight up with me and gave me choices, but said ultimately I would have to have some kind of procedure to fix it.
Did some checking on a few sites and he had the most procedures like mine done and the highest rating.
Make sure you see the right person, has to be an expert when it comes to wrist/hands - extremely complex bone structure in there
