Decided against having shoulder surgery, and bought my own home gym in January. Started doing my own rehab and lifting, basically ignoring the doctors. Not usually a good idea. Anyway, I improved my mobility and the "crunchiness" in my shoulder on my own and finally got back to lifting. Hit 245 flat bench today and 190 overhead press. That's a little more than 10% down from where I left off at this time last year. Bench is down more than my overhead press, which is weird. I'm also in a pretty big calorie deficit now, so I'm hoping that once I get back to eating normally, I'll be able to recoup all the losses.
Doesn't look like I'll be doing the surgery at this point in time.
