Re: pain under breasts
A lot of what you describe sounds like fibro, but it is important to rule out different medical conditions with your doctor. If you have done that, I believe you can attribute your pains to fibro.
When you do not understand what is going on with your body and the doctors you are seeing cannot diagnose your condition, anxiety can be VERY REAL! BUT, many fibro sufferers also have hypoglycemia. When you have hypoglycemia, you can experience severe blood spikes after eating a lot of carb food, or sugar. Caffeine can aggravate the blood spikes because adrenaline is released during the counteract the spike. Caffeine plus adrenaline make a very jittery sensation attributed to anxiety. What helped me eliminate anxiety and panic attacks is eliminating sugar, heavy carbs, and caffeine sodas/teas.
Keep going, and researchingt!
