You might want to have your physician check you for Pulmonary Arterial Hypertension. This condition can be caused by lingering Lymes or mycotoxic exposure that cause low VIP (vasoactive intestinal polypeptide) which among a phlerthora of other things causes PAH. You need to have a VO2 max test and a before and after exercise echocardiogram. In peeps that have low VIP that is getting tripped off to shut down the pulmonary artery (and many things can prompt this cascade- smells, visual effects, substances you put on your skin or inhale, stress, the coloring additive on the outside of a pill) the echo will usually show that the pulmonary artery does not decrease with exercise the way it should. This condition can be held at bay (seems to get worse as time goes by until possibility of heart attack or stroke enters the picture) by taking Cialis- causes the pulmonary artery to relax. The Swiss are working on getting VIP on the market in a spray form and perhaps we'll be able to get it over here in the good ol USA. Refer to the work of Dr Ritchie Shoemaker in Pocomoke MD.
