For the last 15 or 20 shots at the range I was working on hitting my drives harder - much harder then I normally hit.
That night I had some pain in my rib cage, maybe 2 inches below my right nipple. I took ibuprofen that night and the next morning before playing the 18 holes.
From the 10th hole onward, my rib pain got steadily worse and wrapped around my right side into my back.
Two days later and it's feeling 30% better but I'll probably have to rest it for a week before I can play again.
So is this muscle strain? Or is there some cartilage in there that got damaged?
Why the right side? I'm right handed so I thought the left side would be more likely to get hurt.
I golfed in my 20's and never worried about stretching or warming up or over swinging...but I'm 40 now and learning the hard way
