Dear Donna
thank you for the update.

i am reassured by the fact that your massage therapist saw you and feels the problem is limited to muscle tightness.
i had some concerns that the muscular symptoms might be of neurological or vascular origin, but if that were so, there would be other symptoms your therapist would likely have noticed.
nonetheless if it does continue i am glad you will see the doc. as for what he can do, well, for starters, he may want to run some tests, especially if he is unsure if this is due to your fibro or other known conditions.
i hope you can get the insurance straightened out soon so you can get care if and when you need it.
