I have an unexplained rash on my face, including some swelling around my mouth and itching extending to behind my ears. This is the 2nd day I experience this and the 2nd time - The first time was about 6 months ago - I attributed it then to possible excessive exfoliation attempts to help smooth my old face, the day before. This time I can t attribute it to that. WEBMD symptom checker seemed to point me to a carcinoid tumor! Because of IBS symptoms, I ve had several gastro tests to rule out other things, but the attempt to do a pill endoscopy - which was also done to explain a chronic low red (& white) cell & low iron results on blood tests, was not successful since I was not cleaned out enough for the doctor to see what was there. Does carcinoid tumor in my small intestine explain low blood counts along with these facial rash episodes? I am a 71 year old female.
