Trigger finger

I was hitting balls Saturday morning when I felt a very odd and painful sensation. Pain lasted a minute but I can’t move the tip of my left index finger. Have a swollen spot on my palm that I get a tugging sensation when I try to bend it. Read it’s very common in golf, one of the chase could be due to your grips being too small. I use a midsize grip but haven’t put them in my new irons yet. I have been hitting about 100-150 balls most days. Need to get a steroid shot in my hand. I’ll be out for a few weeks. 39 and already falling apart. Just got over knee tendinitis last week.
