Hi I am 63 years old and having pain in the right knee (diagnosed as reduction of space) am also over weight (90 kg). Doctors tell me to reduce weight. But the orthopayic had asked me to rest. If I rest I cannot reduce weight. So I on my own decided to walk everyday. I walk 5 - 6 km daily. While walking I use knee cap and do not feel psin unless leg bends side ways, but while sleeping I do get pain on the left side of the knee (bearable though). I do take biocart-msm 1 tablet one daily, triflex fast acting two daily, and apply celadrin cream 2 - 3 times on the affected knee. Suggest exercises to get rid of the knee pain.
