Louise, this diagx I am posting mimics various symptoms and problems, it is generally made when other things are ruled out.
But, you could have two diagx too...
Read some of this and the forum to see if it fits your situation.

I am posting as you mention the ring and pinkie finger and that is classic to thoracic outlet syndrome ie) brachial plexapathy. The spasms, sore shoulder, traveling to the ring and pinkie are some of the symptoms. The nerve compression is in the area behind the collar bone and in front of the first rib. The symptoms can be anywhere there is a hinges, as the elbow, shoulder, wrist or CT.

This is not diagx with an MRi typically unless a pro doc does a brachial plexus 3-D MRI, maybe it could show, or in the later stages it can affect the nerves that are tested by EMG. TYpically the smaller nerves are the first affected and unable to test by EMG.
I some people they ahve extra cervical ribs or misshaped ribs, even larger collar bone that compresses the nerves as they pass from the certvical spine across the trapoizus into the arm and hands.

I hope you can find relief. I found valium for the muscle spasms helps.
