Thank you Kel, Nonya and Libby,
Kel, I think that the collarbone may be something to put on the list for the year-end rheumatologist visit (only about 7 months left now
). Nonya, you've got me thinking of looking for old photos now.
Libby, I hope the nerve pain eases off for you. Even if there are no nerves between the shoulder and collarbone, can't pinched nerves in various parts of the spine cause pain other parts of the body? From looking at one site (I haven't done much research to speak of), it looks like pinched nerves in the cervical region of the spine can cause pain and weakness in the shoulder, arm and/or hand. Is it possible that your shoulder/collarbone problems cause you to hold yourself in such a way as to pinch a nerve in your neck?
Now after noticing something interesting when looking that up, I am going to go do some research (such as it may be) on the vertebra C8 to see if it could really have anything to do with my little finger problems...and if it all comes down to posture after all...
