I haven't met you, yet, but I'm guessing were pretty close in age. I can relate with what you're saying about your shoulder.
Last September I did something similar. I was using my left arm quite strenuously over a three day period. Didn't give it much rest and did the same thing again for one day the following weekend. What was I doing? Jerking on a muskie rod during a couple of fishing [font=Verdana,Arial,Helvetica]tournaments[/font]. Only thing I got for my efforts was a very sore muscle in my upper arm and shoulder. I thought I'd give it some time and things would get all better on their own.
It continued to hurt me at times during duck season, especially running the mud motor. Then in late december I couldn't properly shoulder my smoke pole. Managed to harvest a deer but it wasn't easy getting the gun up. When my range of motion got to the point that I couldn't even reach my back pocket, or touch the top of my head with my left hand, I finally decided to consult my doctor.
I ended up going to six weeks of physical therapy to regain use of my left arm. Man, if this was thirty years ago, I'd have just shrugged it off and felt fine in two days.
My wife had to ask me "Next time it start it starts hurting, are you going to stop what you're doing so you don't re-injure it?",,,,,,,,,,,,,,,,,,,,,,, I just looked at her,,,,,,,,,,,,,,,,,,,,, Jees, we've been married 34 years, you'd think she KNOW my answer to that one. BWAAAAAAA
