I had a baby 4 weeks ago, the second week I was home I developed a fever and had the chills. It was 75 degrees outside and I had to wear pants and a sweatshirt or I would get cold. I called the doctors and they said if I think I need to be seen to come in I might have an infection. The fever went away with tylenol and It went away altogether about 3 days later. I didn't go in because they didn't seem concerned. The past couple days I have gotten really lightheaded while standing up. Last night I noticed (4 weeks postpartum) when I get up to feed the baby and Im sitting there feeding him I get a pain in my upper stomach and in my ribs. Kind of like an aching pain that gets worse the longer I sit there. Today I am experiencing a weird feeling in the back of my throat. I can take deep breaths but I feel like my throat might be swollen and it feels dry when I breath in.

I thought maybe did develop an infection and it has changed to pneumonia. Could that be possible?
