I'm really worried and need some advice. My son-in-law is having a really hard time with a chest infection that's turned into the worst case of pneumonia. It's so bad that he's on ICU now and struggling to breathe. The doctor currently handling his case is a general physician and seems good, but I'm wondering if we should consult a chest specialist since this is related to chest infection. Do you think this situation is curable soon? I'm just really worried and would appreciate any suggestions on what steps we should take next.
