Ive been having frequent cheat infections . sometimes they happen after a sore throat sometimes they happen without it. my chest gets congested and it doeanot recover even after 20 days. after which the process slows down untill it shows up again as an agravated infection. this started happening in 2015. i was also given a shot to mature babys lungs before my 2nd delivery. when i wake up in morning , the first breath i take deeply feels like there is a fluid in my lungs that disperses wth breath
