I am interested in your site because my son who is 15 has suddenly started having some problems. He has been an avid athlete...MVP Middle School Soccer Play of the Year, excellent baseball player, ran in the 3K and won his division this summer, great basketball player...always a team player. He has recently experienced severe chest pain, trouble breathing, a brown rash across his back and a brown area around a scar on his back. He had a tilt-table test and it showed some bad things concerning his blood pressure...it would drop to 73/23 at some angles and 96/98 at others. It was unsteady the entire test. He said several times he felt like his head would explode. He's an excellent student, a thoughtful boy, and has a strong faith. He has been pulled out of sports for the time being and this has depressed him. Soccer tryouts for high school are next week. He won't see the endocrinologist until Wednesday. I don't know much about this disease except what I've read recently. I can't tell if Drake fits this or not. His dad and an aunt has Multiple Sclerosis and his great-grandfather had Myastenia Gravis. His brother is on growth hormone. Have you seen family's where alot of these things occur? I'll look forward to reading at your site. Please let me know if you have anything to share.
