I recently appear to have all the symptoms of Pheochromocytoma, according to the web. I have been told to stop my Lisinolril a few years ago when I was in the hospital diagnosed with an ulcer. My doctor said to monitor my BP and after charting for 3 weeks @ 3x/day, he recommended taking the Lisinopril if I had a spike in BP. I started a new, very stressful job last week and am in training. I have an on and off radiating pain down my left arm, pressure in my chest, as if someone was sitting on me causing difficulty in breathing,unlike my asthsma. I have on and off pain on the left upper chest near where my arm connects. I have lost 6 lbs in 2 weeks. My BMI is norman and am a non smoker. Have a history of mother with same symptoms and never got the BP regulated. She died instantly of an anyeruism at a funeral where she did not take her BP med since it was low. Her family had heart issues..angina, strokes. I hear my heart throbbing in my ears and have constant headaches in the back oof my head. Can you help me? Thank you!
