Sir my mother aged 66 years is a cancer patient and her treatment is going on TMH Mumbai since March 2012.  Now she has trouble in left knee and feeling too much pain and not able to walk. Her left leg swelled last week. Her blood report for thyroid stimulating harmone is 3.91.  Our family doctor told that this is age factor. I want to know the cause of pain in left knee and to be got appointment with better treatment
Dear Sir, Sorry to hear about your mothers' problem. It is difficult to comment on her status as you have not mentioned which cancer is she suffering from. Arthritis is a common problem in this age group and usually affects the knees, so the pain can be explained with that. But considering her history of cancer, there is no harm in visiting the doctor once and having an x-ray of that area. Hoping for the best.
