I just got back from a cardiologist to get a 2nd opinion as to whether or not I have dysautonomia. I went through the whole spill about all my symptoms and how I feel. He said it was out of his realm, and that I needed to go to the Mayo clinic in Florida. Talk about stressing me out! I asked him if all this could be caused by anxiety, and he said "No, There are several things going on with you. Anxiety may be a factor in it, but I don't believe it's causing it. I would suggest a good internal medicine doctor. If you were my son, I would take you to the Mayo Clinic in Florida." Symptoms for today: chest pain, extreme light headedness, pressure in my sinus cavity and back of head, and not being able to stand or walk long or far without the symptoms getting much worse and needing to lay down.
