Shoulder injuries - need info, have questions (popping? strength?)

A little background:

I wadded in March and landed on my arm/shoulder. Went to therapy and the ortho for 3 months, had tons of x-rays and 2 MRIs, and was diagnosed some rotator cuff damage: a couple partial tears in the supraspinatous tendon and a partial tear in the subscapularous tendon. After 3 months I was feeling pretty good except my strength was about 30-40% what it should be in certain motions (like pulling down from above my head). It took about 2 months just to get back a halfway decent range of motion. I never had any popping in my shoulder during these three months.

The "new" injury:

Then, 6 weeks ago, I crashed on my shoulder again (yeah, you'd think I would stop). This time it was different, took about 2-3 weeks to get back almost full motion but there is no strength again in certain movements. Like I can lift a pencil up from my side or out in front of me and above my head, but give me a 32oz glass of pop and forget it. I can't lift it up past a little lower than shoulder height (to my side or in front of me).

Popping and snapping:

And another thing is my shoulder has been popping and snapping like crazy! Like if I reach out or down for something - I'll get a loud pop. Sometimes I barely move and it does it. Usually there is built up pressure then a pop, sometimes not. And I can hold my elbow out to my side and move my arm like 2-3 inches back and forth and get a pop on each movement both ways. Usually there is no pain involved, but sometimes there is.

Any ideas:

Has anyone had an injury that has a lot of popping and snapping? What are the normal symptoms of a dislocated shoulder? If it's still jacked up after DW (which will be 3 months after crash #2) then I will definately go back to the doctor but for now I'm trying to suck it up and hope it gets back to normal. Does the insane lack of strength sound alarming (it's only in a few certain movements)? I really haven't used my arm much since March other than 2-3 weeks in June so maybe it's just been a long time? I did do some strength exercises in May-June but haven't done much since crash #2.


What a wasted year :|

Just a quick shoulder update - it's been 2 months now since crash #2. And nope, I haven't went to the doc. I'm still being stubborn and waiting until after DW (if it's still needed at that point).

The popping and cracking isn't near as bad as it was a few weeks ago and there is very little pain. Really at this point it is more an issue of no strength in very specific movements and a slight decrease in range of motion. While at Wal-Mart the other night I learned that I can lift a 1 lb. dumb bell from my chin to over my head but I could NOT lift the 2 lb. one!! What a pitiful feeling!! So I've been trying to do some light exercises to get some strength back. My guess is since I haven't lifted anything since Feb., the muscle has just went away?

I have been riding for a few weeks and it's going okay (no crashes thank God!) so I plan to make it through DW then decide my next steps from there.

Thanks everyone for sharing your experiences and the advice. Hope to see ya at DW!
