Just saw your post as I'm heading to bed, so this will be brief....

Don't limit yourself to RSD, fibro, or both.

Your days sound a heck of a lot like my days and I'm TOS, RSD, and fibro (and my headaches in the occipital area with a migraine component are from occipital neuralgia.....all tied in to the neck/upper back pain)

That's not to dx you. Obviously, none of us here can (or should) do that. Just sayin' you might want to look up TOS too.

It took me YEARS to get dx'd too. Whereabouts do you live ? What kinds of docs have you seen and what dx's have they made ?
