I wich you a quick recovery Mike! I understand the pain
I dislocated my left shoulder 1985, my entire arm look like it has fallen out of its joint, possible to put a finger in there. Horrible pain.
I have after that got it dislocated at least 20 times since I did not fix it (surgery add some stopper + shorten the tendon(s). If I rotate the left arm a little upwards or have my arm in wrong angle, left shoulder will dislocate.
Worst memory when I had parked my car, fix the belt on it hanger and the arm dislocated from shoulder. What a pain during 20 minutes it took for me to creep out from the car. When my arm/shoulder is dislocated I need to relax it and hang forwards, twisting the arm in right direction and it will come back in position. Pain is awful!
Important for me to use correct arm when taking a fishing rod appart and the upper part of rod will pop out very abrupt together with a quick heavy dislocation!!
