Hi

I'm not a physio, but I've had frozen shoulder 3 times. That's whar your description sounds like. My frozen shoulder was caused by nerve problems in neck. Nothing actually wrong with shoulder itself, although thats what it feels like. Frozen shoulder usually lessens its intensity after 3/4 months and gradually disappears after 10 months, without any exercises or interference. Its just muscle spasm referred from neck. One sure way to help it last longer than it should is to engage in testing exercises which simply return the problem to starting point and the cycle of recovery must begin again. If it is likely to be frozen shoulder, then an MRI of neck area would be more appropriate to discovering cause.
