I've been playing golf for almost 20 years and developed a fairly consistent swing over the years. I shoot in the mid 80s most of the time, and have more rounds in the 70s every year.
About a month ago, I suddenly started shanking shots with mid and short irons. I've done a lot of research, read about causes and fixes, watched several instructional videos, checking my grip, my posture, my swing paths, everything, but it still happens occasionally. My last 2 games had been horrible, I was so afraid of hitting the shank, my irons now suffer 1 of 2 things: Half of the time I either hook my irons left (I'm a righty), or the other half of the time trying hard not to hit with the sole of the club ending up hitting too soft and ended 20 yards short of the green into hazards.
It is so frustrating that I normally could hit the green anywhere from 170 yards in, now I can't hit the green from any distance, even with a pitching wedge. I usually hit 10+ GIR per round, the last 2 rounds maybe 2-3 GIR. I'm not a long hitter which is why I rarely ever loose a ball, but the last 2 rounds, I've lost a lot of balls with the iron shots, I've played 3 off the tees from many par 3s from either hooking into bushes or O/B, or hitting short into water, etc.
It got so bad that I don't want to play anymore, I think my issue is the mental block, I keep seeing an image of shanking a ball that I can't even swing a club properly anymore.
Please provide suggestions on what I can do to bring my game back to normal.
