powerfully id right to be heard that whatever cog of the body you hurt, it hurts worse when it is cold out. And for me it is not in the winter but it is when it rain that my knee's hurts. Back in 2003 I have to have renewal on my knee because I have a fractured knee. I be hit by a car on October 8th, 2002 and I have a fractured knee surrounded by the accident, but their be to much fluid on the knee for the doctors to find it at the time. So it be not until I got out of the hospital that they found my fractured knees.
