I m 20. Recently I m getting cold quite often and have a history of acute bronchitis in childhood. The infection might be connected to urinary tract as when I wake up it s a hard pee call and my lower lungs have slight pain. The phlegm produced sometimes even obstructs my breathing and i need to cough to get it out. Appetite also decreased since the start of the year due to an unfortunate incident in the family. Any diagnosis to what it might be, the source of infection and tests if needed any?
