How long does it take you toťillness?

I guess what I mean by recover is to return to mostly your basic level of extreme fatigue. I just fished my antibiotics for the pneumonia I was unaware I had. It was an incidental finding and being dropped off at the ER for severe lower abdominal with extreme fatigue and lower leg edema. In fact I have been trying to type this for over 20 mins and keep passing out.
