Can anyone suggest how to make easy ayurvedic recipes or an ayurvedic book that is worth purchasing?

I am a school teacher. I started experiencing muscle and joint pains since I turned 43. I have to correct a lot of papers, write on the board and climb the staircase every day. I have taken by homeopathy and allopathic medicine. This has reduced the pain to a certain extent but not completely. One of my colleagues said that I could prepare my own medicine. Please suggest me the formula for preparing Ayurvedic analgesic oil?
