Take care of your shoulder! I waited way too long to take care of mine (and seriously, that was with surgery a mere 9 months after the injury). I lost SO MUCH strength I never got back.
(Although that said, the one I had surgery on in 2008 is bothering me again, and I haven't even done anything to it this time).
I have the normal recurring tendonitis, but the bigger problem is being unable to shake a cough I've had since 1 February and climbing pollen counts. I wasn't doing much, but I miss my Pokemon walks, and weekend light hiking.
