You know, when I used to have a lot of anxiety, I would feel like that. I thought it felt like my blood was boiling! So, this could be your anxiety, too, and your Mom sure isn't helping with that, is she!
But, do discuss it with your doctor. If you can see a rheumatologist who believes in fibro, they would know more and could answer your questions better.
Hope you feel better soon!
