High BP

Just wondering if anyone has experienced similar problems to me:

I am 22 year old male, recently diagnosed with high BP and put on 10mg of Ramipril and 5mg Amlopidine. I was reffered to the cardiologist, so have recently undergone a MRI scan, Ultrasound of the Kidneys and a 48 hour urine test. The cardiologist is testing for both narrowing of the aorta and pheochromocytoma.

When the cardiologist measured my BP, my left arm was significantly higgher than the right - has anyone had any experience of this and if so what was the outcome?

I took my BP and hear rate this morning, my left arm was 159/128 and the right arm was 135/89 - anyone know what this could possibly be, or has anyone else experienced similar and just come to a dead end?

Many Thanks
