You will never conquer golf.
Hope this don't sidetrack the thread too much. If so we can delete this and fire it up somewhere else.There are some things you could do to remedy this...
#1. 16oz ball peen hammer on that knuckle. Hit once, HARD. It'll only hurt for a minute. Then you pass out. No more pain. Then you wake up, see a doc and have it set into the position you want it to be it. Once the bones fuse, you're all set. No problem.
You don't want to do #1.
#2. Adjust your grip so you're not suffering pain from your swing. A good golf instructor will work with you and your physical limitations.
I know it was either @Luchnia or @chile that improved their swing speed during quarantine by a couple or even a few MPH... maybe they could say how they did that.
There's the saying "no pain, no gain" and "pain is weakness leaving the body!"
I'm a BIG fan of "no pain, no pain."
If you're experiencing pain after golf something's wrong. That shouldn't happen. That's why I suggest you change your grip to accommodate your arthritic knuckle.
My driver was average about 93 - 96 through the better part of this year up until about a couple weeks ago that I reached my highest speeds and now I have gotten to an average of 100.9 driver the last three times I have checked. I would feel comfortable saying it was probably a good 98 now.
I don't know how long it will stay there as I am not a young guy anymore, but so far it has hung in there for a couple weeks now. These speeds are checked with launch monitors so they can always be give or take some, but when I was fitted at CC for my irons their data matched mine so aren't off much.
I have done a number of things to attain the extra speed, but I was told as you get older you lose swing speed, but at 66, soon to be 67, I have gained speed so it can be done. Now I will state right away that I normally play a bit reserved on the course so my guess is driver is around 98 on the course. The rounds I have played the last couple weeks my irons yardage has increased and I have been overshooting greens. I have gone from a 100 GW to 110/120 and can easily go more if I really pepper it. It all depends on how the body feels on a given day though.
As for how I got there. Here are the things I have done and I am not sure which actually did the most for me. It may be a combination of things:
1. Started better diet, exercising more, and lost some weight. This has helped immensely.
2. Started stretching every morning and at the course to loosen up better - if I have tension, my swing and speed suffers
3. Practice with the launch monitor every day that I could and worked on increasing speed as well as a more quality ball strike - sessions were usually 30 minutes to 1.5 hours. I would do long sessions if I did not wear down, but normally 45 minutes of hitting balls is about it for me. I worked on really feeling the weight of the club as it passes through striking the ball and using the muscles in my back more to create more velocity through the golf ball
4. Changed my wrist position some in my backswing and totally shocked me how much this helped for ultimate speed, but this caused some control problems
5. Used those alignment rods you buy at Lowes and practiced the whip feeling (haven't used these in a while)
6. Used stretch bands to strengthen my arms (my arms are not very strong so that helped and I haven't done this in a while)
7. Stopped telling myself what I could not do and worked toward a goal of doing it.
