Why would my asthma worsen so severely in the last 2 months? I live in N Florida- allergy tests show nothing.? I've had asthma all my life. I'm 26 years old. In the last 2 months, it's gotten much worse. Nothing major has changed and allergy test show nothing. Just 2 months of chest pains - thought I was having a heart attack, even. Hospital visit proved otherwise. Can't hardly breathe. 2 Xrays are clear. Lung function @ 40%...currently sick/lots of mucus/blood...any theories out there as to what would cause acute chest pain an worstening asthma in the last 2 months? Meds: Advair, Xopenex. 

*Past Triggers: Stress/Weather (never many allergies - testing yesterday reconfirmed this)
*Mucus is awful at night/in the morning - spots of blood now in mucus (maybe coughing so hard?) 
*Bad wheezing (mainly @ night - during the day sounds "clear" to docs)
*Chest pain is a squeezing feeling in center of chest- worse when lying down/on side - no evidence of cardiac issues, and asthma is much worse (2 docs suspect asthma likely a strong tie to chest pain)
*I don't smoke. Nobody in my house smokes.

Summarized question: Can asthma worsen as you age? Can asthma cause acute chest pain?
