I am seventy four years old and a pensioner. Because of my bad knee, I am unable to function. I am in a lot of pain all the time awake and asleep. This prevents me from living a normal life : I cannot climb stairs, have great difficulty walking, gettng up from a sitting position, bathroom activities, etc. Pain killers no longer work. A knee replacement was recommended but I have no funds, no medical insurance. This service is not offered at our public hospitals. I would be grateful for your assistance.
