My dad was recently diagnosed with sepsis, landed himself in the hospital for damn near 5 days. He just came back and is recovering, given 4 weeks worth of antibiotics.
He doesn't English, so I need to figure out what his recovery symptoms are so he can explain them to his doctor.
At night, he has hot and cold flashes.
There's also a region that feels very hot in his left lung. Around the area highlighted in picture. I don't know what this is.

Apparently these wild temperature swings don't happen during the day though.
