You are welcome, yankee. Tlokein sounds as if he has a serious problem, at least, troublesome. It may be nice for him to try going to a higher altitude for a bit, just for a period of RELIEF. Dust mites etc do not exist at higher altitudes, as well as other allergy/asthma triggers. It just might help to give his immune system the time to heal a bit. Of course returning to sea level may bring back symptoms but at least he would be starting from a better starting point. A trip like that could be costly, though. The other thing for Tlokein to do is to consult with a board certified ALLERGIST, a second opinion other than ENT--they have different approaches to allergy problems.
