Severe Shoulder Problems

My hubby is an idiot at times. He's a DOCTOR!! You would think he admit when he should see one.

About 4 months ago, he helped me power-wash the RV. About a week later, he took some long measurements and had to crank in the measuring "tape". A week after that, he was driving his golf cart and rammed his already aching arm into something.
His shoulder gave him severe pain after the first event, but it became progressively worse.
At one time he couldn't lift his arm. He couldn't hold a can of coke.
Today, he was unable to pass a plate.
I've been telling him repeatedly to see a doctor, but the man is HARD-HEADED beyond belief.

He performs surgeries every Tuesday (Cataracts and such), all day long and comes home barely able to move his arm at all.
He says it's been getting better, but how much time does he need?!

He's 66 years old and otherwise relatively healthy (he takes high blood pressure meds and antibiotics every day and has for years).
To ease MY mind, what damage was most likely done?
If I can show him possible reasons or intellectually SHOW/explain the reasons for the pain, he *may* be more prone to have someone take a look at his arm.

Your hubby might not want to see a doctor because of pride, not stubborness.

He is a doctor, and may not want to be treated like a layman by another doctor, who may be much younger than himself.

If he can't hold a can or pass a plate, it may affect his ability to do his job or drive.

Yeah... that's part of it. Another part is despite his genuis he can be a bit paranoid. He doesn't trust local doctors. There's a lot of small town politics and he doesn't want to give them something to talk about.
Another part is he's too smart for his own good. He knows the local doctors have horrible track-records with things like colonoscopies and other surgeries.
But I try to tell him that even they can run an X-ray machine and do a general chack-up. If it turns out to be something serious, he can make an appoinment elsewhere.

For his surgery day, he's fortunate to have a very well trained staff and that's he's able to rest his wrists on the persons head. He doesn't have to stress his mobility.

Maybe he should try to do conditioning exercises?

Ligament damage may explain his inability to hold a can or a plate. If he has nerve or ligament damage, conditioning exercises may cause further pain and damage.

I am assuming that being a surgeon, he would have the highest level of private health care?

If so, he can choose a good hospital for surgery, so he doesn't have to worry about the competence of local doctors.

I don't think anyone in this forum is qualified to give professional advice. Maybe you can visit a doctor(s) yourself, and ask for their professional opinion(s)?

Thanks :)

He had me pick him up an arm sling at Wal-mart the other day. He wears it all the time when he's home and he *says* it's helping.

He just irritates the dickens out of me. He had a hernia SO BAD for so many years his testicles nearly hung to his knees before he FINALLY broke down and had it repaired.
I'm just worried he's going to put off seeing someone about his arm and end up making it worse and irrepairable.
