My son is 26 years of age, is treated for moderate asthma and has tried three commonly used
OAB medications, Detrol and two others.

All of the medications seem to cause some tightness in the chest that makes him discontinue
the OAB medications.

Has anyone experienced this difficulty?

Seems that the meds effects on the bladder's nerves may have some of the same effects
on breathing.

I wonder if Botox would have the same or more dangerous effects?
