Unable to do OH work

[Auron]

Over the last few weeks (about 4?) I have been unable to do any OH work, I get a pain down the back of my right delt, it is not actually in the joint but runs down the muscle. It started when I had spent a weekend sanding a car down. It doesn't seem to be getting any better. With any other kind of movement you would not even know there was anything wrong. Complete rest seems to make it worse.

Would you presume that it is a rotator cuff problem?

Sounds very similar to the pain I had when my rotator cuff went - no pain at all most of the time, then try anything above shoulder height and it was like being stabbed...

...what worked for me was face pulls, scap pushups / pushup plus, dip shrugs etc - anything that strengthened the rhomboid - as well as the usual RC stuff such as cubans, PMSH, prone letter drills / YTWL's etc. (with very light weights and in some cases no weights at all) as there was fairly major associated scap winging (and indeed still is).

Also it's not a case of, you can stop doing this once it's "better", because I did that and then I got the same problem pretty soon after - my advice is to include some of the above in every session from now on...

Might possibly be a muscle imbalance.

Go see a sports therapist would be the best advice over the net.
