Tru,
Hope the ribs heal quickly. I think most people on here have had broken ones at one time or another. I used the Warren Method and slept in a recliner for a week or so. Nothing but rest is going to heal them. Oh, and the less you breathe the better.
Whatever you do, don't take a drink and then sneeze and have it coming out of your nose and everywhere. That will take you to a level of pain that I don't think they have a measurement for.
As for the heat, just turn on the air conditioner, get something food to read and relax. I know, easier said than done.
Ron
