What Causes Severe Pressure In The Head, Swelling In The Eyebrows And Cheeks?

Hi. My name is XXXX. I keep getting a feeling of severe pressure in my head. As the pressure escalates I get a headache that does not respond to over-the-counter medication. When it continues I begin to have swelling above my eyebrows and in my cheeks below eyes. Total relaxation usually helps, but not always. My doctors are aware of my situation and are running test. I was born with heart problems and I m wondering if it could be my heart, and why my doctors and the hospital aren t being more aggressive with my treatment. I feel like I m not being taken seriously. I m also concerned that it could result in permanent damage to my overall health. I m hoping that you can give me a peace of mind.
