Has anyone else dealt with pneumonia? I was doing so well until it hit. I'm 52 and completely healthy other than my CF lungs. It has left me needing supplemental O2 for the first time ever. I really would like to know how long to expect to need it. All other symptoms are resolving after 3 weeks on IV antibiotics. I'm walking 20 minutes per day while wearing 02 to try to build back. Any other suggestions?
