Hi, I have developed hard lumps on outer side and at the bottom of both knees. They are only noticeable when bending the knees and to date are not painful, present for approx 2 to three years. As well as that I have an undiagnosed illness/disease for which I am still trying to find an answer. Tests, appointments are ongoing (undiagnosed for over three years since first onset of symptoms). There could be a some possibility that I may have a form of Scleroderma, at this stage I don t know which particular strain that might be. My question is: Could there be a possibility that the very hard and painless lumps may in fact be related to calcinosis (calcuim build up) which can be one of many symptoms of scleroderma. Thanks very much for any advice on offer SORRY, I AM A PENSIONER, THOUGHT THE SITE WAS FREE, PLEASE DISREGARD MY QUESTIONS
