Your shoulder does not have to be fully dislocated, it can be partially dislocated, this is called a subluxation. If you continue to train with the bone out of place, you will do a great deal of damage to the joint, it has to be put back in place by someone qualified to do it correctly.
PLEASE DON'T TRY TO DO THIS YOURSELF. You could do permanent damage.
The head of your humerus, (upper arm bone), has to sit in the joint absolutely right, or it will tear all of the cartilage apart, and you will be left with bone grinding on bone. You might be crippled for life.
There is a guy who is a regular visitor here at Next Level Formulations, bodybuilder and trainer here in the Denver metro area, he is in his 50's, super nice guy. Anyway, he dislocated his shoulder about 15 years ago, and never had it properly treated, now he cannot lift his right arm much higher than his chest. Don't let this be you.
MJ, I remember that you have had bad experiences with chiropractors in the past, and that you may disagree with me on this point, but you really need a good one right now.
Please believe me, I've been involved in training for over 25 years, and as a high school coach, I had the opportunity to train thousands of people, I would not try to steer you wrong.
Call around and find a chiropractor that is also a lifter, this might take some work, but it is well worth it.
I really do hope that your recover from this completely, because you have taken proper care of the problem right now.
Most problems in lifting can be solved by either pulling harder, or pushing harder.
