I was encouraged by my psychiatrist to write to the cardiologist who saw me may 20th about additional concerns: palpitations, extreme breathlessness on minimum exertion etc. I do have Chronic Fatigue Syndrome/Fibromyalgia. Long list of symptoms. I received a letter today with the report sent to my GP from Cardio Doctor. It said that i had a flat blood pressure response. I didnt know what it meant so stupidly I GOOGLED slap myself. All I saw was heart failure and i got myself into a right state. Does anyone know what flat blood pressure response means. While I await to go for an ultrasound.
