Okay, the pain on my left side has now become a sharp pain in my lower left lung whenever I take a deep breath

What the fuck body, what are you doing

No fever, oxygen levels are fine

I'm going to go lie down some more

Yeah I've looked around the net and it's either muscle strain or maybe a minor pneumothoriax. No fever, good oxygen, blood pressure is normal, no fatigue or dizziness or nausea.

if it doesn't let up I'll make an appointment with my regular doctor

also I'm only 31 and 115 pounds, so a heart attack is almost impossible
