Etabic,
I'm glad you're getting better, but I'd like to clarify a bit about pneumonia by sharing something that happened to me.
I has a few "allergy exposures" like you did. I got pretty sick, even coughing up blood right after the last exposure for about a week. I had lots of mucus, but no fever, and felt very "fluish." I had trouble coughing out the mucus because it would start to bleed. I knew I was in danger of pneumonia with the bacteria not getting out. I started extra treatments and changed up my meds that were less irritating to the lungs.
I had 2 cortisone shots to open my airways and get the plugs out which I could feel. With cortisone there is also a danger of Pseudomonas growing. So I went on Tobi, because we didn't have the results of a culture, my doctor was going out of town for 2 weeks, and I didn't want to get into trouble. And I felt horrible. This went on for weeks. I started to get worse with a low grade fever. The doctor returned, and was surprised that the Tobi did nothing. I had an X-ray at a radiology facility. The radiologist said there was no pneumonia.
My doctor said she wanted to look at my X-rays, and now the culture, and blood tests were in. Very high white count, the culture showed nothing (which was shocking). I used to always culture P.A. and frequently staph.
When the doctor looked at the X-ray, she saw the pneumonia, right about where the diaphram is. She said radiologists arn't pulmonary experts and they didn't have a comparative X-ray.
She said that she was pretty sure it was what is called community acquired pneumonia (garden variety pneumonia that normal people get). She gave me a couple of Z paks. After the first pill, I felt better. It went away fast.
The point is pneumonia isn't always picked up. And depending upon the circumstance, oral meds can work great. Another doctor would have put me in the hospital. And it would have been for nothing!
The second point is, when you have a serious exacerbation, I would consider seeing a specialist right away. I had inflammation. I couldn't get the mucus out. The doctor told me if it went on too long, it can turn into infection and pneumonia. For me, that's what happened.
