Please pray for me. My left knee is very, very painful and I cannot take the pain any more. I have been through too much the past three years with infection that took my right hip. I had to wait a year for a new one. Blood clots in lung and right knee. MRSA. S pent nearly four months in hospital and nursing homes. I am in a wheelchair and cannot really walk or stand more than a few minutes because of three spinal problems. Thank you, Mary
