You need to get to the ER. Don’t wait til tomorrow
Thanks for your concern. I just put him to bed and looked at his red streak, its the top of a humongous black and blue, so the lower part is black and blue and the upper part is red. I think he’ll be OK til the nurse comes. His incision has been covered since Monday when they did the surgery. If she doesn’t look at it tomorrow I will make her. The heat in the knee is a new development today, and I’ve been there myself.
