We did some things right on our visit and learned from some mistakes. The next time we visit, I think this is what we'll do: 1  Leave Disney World about 90 minutes before Kennedy Space Center opens.  Drive to KSC, get parked, and be ready to enter when it opens.
Pulmonary embolism is the most feared cause of chest pain when breathing. Pulmonary embolism is caused by blood clots that go to the lungs mostly from veins in the leg and get lodged in the blood vessel of the lungs. They can produce inflammation in the lungs that can irritate the nerves in the pleural membrane. This results in chest pain when breathing.
Normal breathing is usually a combination of the two. Chest breathing is relatively shallow. The chest expands and the shoulders rise as the lungs take in air. In the fight-or-flight response, a person tends to breathe more in this way, even to the point of holding the breath or exhaling incompletely. Breathing thoracically can cause symptoms such as shortness of breath and tightness in the chest.
