I suffer with shortness of breathe and gasp for air at times . I have hernia and panic disorder and think I'm dying soon .what is the cause for this?

Panic: You say you have panic disorder. That certainly can cause marked shortness of breath and a feeling of impending death.

If it hasn't been done, I would start with a chest x-ray, oximetry, spirometry, echocardiogram, EKG, and event monitor. ...Read more

Why do people yawn? I heard yawning is a sign that your brain isn't getting enough oxygen. Is this true?

For many young adults, we have great cure rates for those with non hodgkin's lymphoma. The same disease in the elderly, though, is very hard to treat. ...Read more
