Speaking of injuring oneself, I did something over the weekend. My Google self diagnosis is that is probably a rib muscle strain (intercostal muscles). I don't think it's super serious, because my pain is mild, and I have a pretty low pain tolerance. But it's definitely noticeable if I cough, sneeze, or move a certain way. Anyone have experience with this? I've limited myself to walking for exercise the last couple days, and that doesn't seem to bother me so I hope that means it's not bad for recovery.
