Have u ever experienced cramps in your forearms that makes you fingers cramp into a fist, or your arm and hand get that tingling felling like its going to sleep.
Definitely have experienced this. I remeber about 4 years ago I did a New Years gig, and I had to set up by a huge picture window and I could feel the cold coming through. And mind you this place was right across the street from the Ohio River so you know it was cold. Anyway, I did the gig and after about 4 hours we got to the end of the set, and my body just locked up.
Between sweating, and the cold, it was not good. I honestly couldn't finish. Good thing we were pretty much done. The crowd was demanding an encore. I just couldn't do it. Fortunately, the bass player could play drums, and the guitarist switched to the bass. After the gig was over, the bandleader came by the window and when I explained to him about the cold and he could feel it for himself, he understood. On top of that, I had to drive us back because no one else could stay up.
When I finally got home and got my gear in the house, I finally got into the bed and got some rest. The next afternoon, I finally got up and I could barely move. Once I got another hot shower, I finally got myself right.
I've also had the occasional cramp in the thigh, blisters on my fingers and hands, and I've even hit myself in the eye with a stick.
The sacrifices we make for the art.
