Good Morning, Fort the past 2 months I have had chest pressure, rapid heartbeat and mild difficulty breathing. I have seen a doctor and he ran blood tests and did an EKG. The EKG was normal and my blood was all good except slightly high iron levels. He ran another blood test to test for hemochromatosis and said it was negative but wants to check it again in 2 months. I had a treadmill stress test on Friday and it was normal for heart disease and blockages but I had numerous palpatations, so we may do a 24 hour monitor and an ultrasound. On Friday I noticed a slight numbness in my lower left lip, but I can feel it, it s not totally numb and today the tip of my tongue is numb. I have an appointment with my doctor later today, but wanted to get another opinion. Should I be worried?
