Your prosthesis can last for many years, provided you take proper care of it and have it periodically “checked and serviced” by your prosthetist. Weight gains and losses significantly affect the prosthetic fitting, requiring adjustments or even a new prosthesis. If your prosthesis causes you pain, skin irritation or redness that does not go away, contact your physician or prosthetist. They will recommend adjustments or that a new prosthesis be made for you if the present fitting, function and comfort are not adequate.
