When I was about 23 I was walking around a shop where I was the mechanic, and slipped in some drilling mud someone spilt on the ground. Had a new pair of jeans on so I tried to catch myself and jarred my elbow. Well it was sore, but harvest was going so just had to ignore it. Worst was to shift a gearshift in a truck down. Almost piss yourself everytime you would pull it downwards. If yu kept your elbow in towards your body it hardly hurt though.
Well went to see a doctor after harvest and he stood about three feet away looked at me and diagnosed it as arthritis. I told him I fell but the old prick couldn't be told anything. Two years I was taking naproxen and some other arthritis drug that just dulled the pain. Had to mechanic in the winter using my left had as pulling a wrench hurt like hell. Couldn't hold my kids for more then a couple minutes.
Went in for a sinus infection a couple years later and had a locum doctor. She checked it out and jumped when I moved my arm when she felt my shoulder, She said something is broken in there! So had an arthrogram done and sure enough extensively torn Labrum. About three months later went in for an operation. They had to repair a partially torn rotator cuff, extensively torn labrum and a partially torn bicep muscle. The doctor post surgery told me I had bad arthritis cause it took so long to diagnose. I gave my first doctor a royal ass chewing when I saw next time!
Well about five days after surgery had a neighbor leave some bales out in the field and Dad told me to move them. Five days is enough healing after surgery I guess. Well screwed it up and was about 2 months healing after that, went to work in the oilfield and arm was good. It remained good until a couple years ago. Absolutely no pain whatsoever. Strong as it ever was. Arm never had an ache until I hit 45, then where your clavicle attaches to the shoulder became arthritic. Then a couple years later tore the crap out of it again.
Point of my long winded story is I got 20 good years out of the shoulder before I had any trouble. That was with no physiotherapy, doctors or any kind of help just hard work. I am pretty sure Klef can do better then I did.
