I cannot say that I'm all that thrilled with the outcome of the visit there, and my chest is still aching as I continue to cough, but hopefully progress has been made.
While the doctor didn't send me for a chest x-ray, as he said that my lungs sound clear, he firmly believes that my condition is still the persistent allergies. To that effect, he has prescribed an inhaler and a new allergy medication for me to take regularly. He wasn't all that keen on giving me an antibiotic, since I've had so many of them since the start of March, and that's understandable. He did say that if this persists, I may have to go back and have my allergies re-evaluated with a specialist, and then go from there.
Anyway, we'll see how I'm doing in a couple of weeks.
