Post pneumonia 7 weeks now. Lower left lobe. Right had small fluid. Ct scan showed clear left lung and right had small inflammation at bottoms. Feeling weak and at times cold thru my body. They did labs and everything is normal. Even inflammation blood work came back negative. Started using incentive spirometer this week. Started feeling back to my normal self. But today and yesterday had minor set backs feeling cold. Anyone else experience this? I am 34 yr old healthy (prior to this) female. Never gets sick. Until now.
