odd symptom

Dare I say, I'm starting to feel better .. however, I have this weird symptom.. Its almost like I'm about to be developing a bad cough but it never does.. In the back of my throat, it feels  like there is a little mucus or something there.. and my chest feels tight when I breathe in. I noticed it yesterday when I decided to go out.. I went to best buy and I almost felt like I was having an asthma attack ( i dont have asthma)... so tight.. could this be related to any of lyme,babs, bart or my meds- doxy,plaquenil, rifampin

That's what I was thinking. I have something called LPR or silent reflux. I had it way before lyme...  The doxy I am on have made mine act up a little.

Could it be yeast?
