anyone ever have pneumonia

I have been ill since january 12th th, went to er on the 14th had a bunch of tests , was told i had a bad chest cold, however with the meds I still felt no better, i saw the doctor on the 18th , at this point he told me I had pneumonia, now I have sick since, I have been using antibiotics , 2 different kinds, also prednisone and the nebullizer, I find myself not as congested as I was, however , I have not been able to cough up any Flem, I have blown it out of my nose. I now have a little cough not as it was before, but it happens more so when I am laying down, still no Flem I do not feel the wheezing either anymore, . My fear is something else going on here, I do have pain in between my should blades, sometime when I breath and most of time when I lay down and there is any type of pressure to my back, like right now I sit here and type and i feel the ache there.if anyone has had this , how long did it take before you felt well again. I feel like crap, very very tired runned down, and I have never seen myself look so pale before.
