Polibeth, I'm not trying to scare you, but I don't think you've been taking this pneumonia seriously enough. Pneumonia is no joke. The last therapist got pneumonia. The only sign she had was a slight pressure in her chest. She went to the doctor, who listened to her chest and said she had to go to the ER, and they said she had to be admitted. She ended up having to have part of a lung removed, her spleen ruptured, and she was on a ventilator for an extended period of time. At one point, her heart stopped beating and she had to be resuscitated. She had multiple surgeries and a tube to drain fluid from her lungs. When she was finally released from the hospital, she had to go to a rehabilitation place because her muscles had wasted away to the point that she couldn't even lift her arms. She experienced panic attacks because she was terrified she'd get put back on a ventilator.

Anyway, I'm saying all that because I really hope you will take it easy and stop trying to rush yourself so you can get back to work. That's likely to make things worse which could have worse consequences than delaying your return to work.
