Hurt my back during the week and tried to golf this weekend. I was only able to make a half swing with a flip at the end. I was struggling to get off the tee box. The only thing that was working was chipping and putting. I did discover on hole twelve that if I set up with an open stance and swing I was able to get all the way through and get my hands up behind my head. So I started playing for a fade and was able to finish the round with much less pain.
It also didn't help much with the 95* heat and+90% humidity. I lost like 12 pounds walking 18.
