omg, i thought i was the only one. i keep asking on here and on fb if anyone else has these symptoms. 2 months ago immediately after eating i felt nauseous, really weird (light headed maybe) not sure how to explain it, tachycardia, the burning that lasted for about 30 seconds at least 7 waves, the burning was in my arms, back and chest, i peed several times during that episode. anyway, i went to the ER, my bp was 112/32.. they gave me sodium chloride through an IV and then I went home. I felt horrible for a week (i stayed with my mom and dad during this time). when i had gotten home, one night i woke up with high heart rate, feeling weird, burning and my bp was 139/80... which is high for me because my normal bp is 112/58. i ve been having these burning episodes since being diagnosed with dysautonomia. i was wondering, did i have the burning before the lexapro. i don't remember. i ve tried to quit taking lexapro, gradually, but i get real sick... which i was before lexapro and metoprolol. i was put on lexapro to help raise bp and metorpolol to help lower my heart rate. i just seen bev karabin (grubbs partner), i told her about the burning and how no one, not even grubb is trying to figure out what this burning is. grubb thinks it could be mast cell, but bev is doing labs and 24 hr urine (24 hr urine for serum metanephrine test, 5HIAA, and Chromogranin A) to rule out carcinoid and who knows what else. i will keep you posted. and if you want to add me to facebook, feel free https://www.facebook.com/darlene.kinsman
