I have joined the club people. Been playing for just a couple of months now (late starter at 41) absolutely loving it, been told by every seasoned golfer I meet your gonna need lessons. So I booked six week course of group lessons starting last Wednesday it was my day off so went for a round in the morning chilled in the afternoon and lesson in the evening. Arrived at the range PGA pro busy so hit 50 balls then start lesson hit some balls for pro to see my swing, he changed a few things in my swing seasoned golfers spot on this guy is a miracle worker hit another 50 balls with a very big smile on my face perfect height and distance. Then bam I think I have been stabbed in the ribs serratus anterior strain, been nearly a week now and still painful standing up and turning in bed breathing not to bad now going to have to put the lessons on hold for a bit now but it is so frustrating after such an improvement in my game just after a one hour lesson. I think most my problem was doing too much not stretching and maybe the change in my swing (which is no fault of the pro) well I will rest for another week and see how I go.
Sorry for venting my frustration on you poor people just reading this thread made me realise its not just me.
Cheers Spen
