I have tachycardia, fibromylagia, and spinal malformations. Just this year, I developed anaphylaxis on three separate occasions immediately after eating. (I didn't know to ask for a tryptase test at the ER at the time). All food allergy tests come back negative. My skin has splotches that come and go after eating anything or bathing. My hands and feet swell everyday, more so if I'm doing walking or anything but resting. The docs all think that it may be autoimmune, but I haven't had the testing yet to determine anything (waiting for scheduling). Any ideas come to mind of tests that I should request?
