Niggling Knee pain on either of the legs

I am having Niggling knee pain either on left or right legs. It started about a week back without any physical damage where it started on left leg for 2 days, shifted to right leg for 4 days and from yesterday it's back to left leg. I had a home remedy of applying a mixture of Turmeric, Sugar and Lime powder over night for last 4 days which is giving me relief.
