My neurologist and the pharmacist just told me to stop taking it. I haven't talked to my neurologist recently. My PCP did a chest x-ray and it came back normal so he referred me to the pulmonologist.
My pulmonologist did some breathing tests and ABGs but those were pretty good too. He put me on some nasal sprays for congestion in my nose but that has had limited benefit. Most recently, he ordered a special CT of my lungs to check for damage to the lining of them, etc. I am still waiting on those results.
