Today I had an episode where I was in the bathroom with diarrhea and all of sudden I experienced a flushing experience in my upper body’s. My fingers became very hot and my face flushed and swollen. My lips swelled also. My tongue became large and felt part of roof of my mouth right side swell. I took Benadryl. I had only had toast and coffee to eat. This was around 12:30. My finger tips are still hot but not burning. I have rash on cheek. My lips are up on right sight. I had heart attacking in 2008. Have hypothyroidism, discoid lupus,fibromyalgia and irritable bowel among other things and just saw my primary care three weeks ago. Should I be concerned?
