It was a deep throbbing, Jim, it seemed like it was kind of matching the pulses from the cutter engine that I could still hear in my mind. Probably just abused the muscles. The pain would subside after the hot water, go back to being a slight dull ache, then it would get going again and start to radiate around to my stomach and I knew it was turning bad again. I wondered if it might be a kidney stone or something, I hear that's bad, but I'm sure it was from the exertion running that cutter through nasty vines all day.
