question: Hello...  I wake up in the middle of the night and while I am laying down I gasp for air.  I am a 56 year old woman. I weigh 120 lbs. and have always been very active. This concerns me. In addition., I have tenderness in my ribs as well.I have allergies and do cough quite a bit. I have always been very healthy. I don't feel ill.... I am just concerned about what's going on. Your help is greatly appreciated.Respectfully, Jill
