Mike from Fit for Golf has golfers elbow/tennis elbow fixes for you, so will not comment on that. I thought I had it until I started having issues with my arm and hand, particularly nerve related. After a lot of Dr visits, I found out I had both carpal tunnel and a severely impinged ulnar nerve. Carpal tunnel is easy to fix. The impinged ulnar nerve, not so much. By the time it was diagnosed, I lost use of the hand, particularly the left pinky, ring finger and middle finger. The hand is numb as was most of my left arm. Surgery solved the impingement but I missed the entire 2022 golf season and may struggle to play early in '23. Nerves heal very slowly (1 yr +). Lots of PT and daily exercises.
The point of this is that if you have tingling or a bit of numbness/discomfort in your hand or wrist, especially towards the outside of the hand and pinky, get it checked. Go to a hand specialist, have an EMG test done. Letting it go too long causes longer term issues. And hitting balls off of mats, particularly a lot, can cause this over time.
