Oh, Carole, I'm sorry to hear of you and your family's health problems. Prayers and good thoughts on the way.

Just remembering how, many years ago, my son came off a motorbike and damaged his arm. His elbow was out of joint and he had what just seemed like a bad gash but some sort of infection set in - won't go into detail but it was vile - that just would not, despite treatment, heal. I remember the doctors saying it was some sort of blood infection. Even today you can see the hole/depression in the skin where it was.
