Osteoarthritis is a very painful condition of the joints, typically effecting the knees . This can make walking and climbing stairs difficult. At times pain killers or anti-inflammatory drugs are needed, although some people find strengthening their quadricep muscles (also known as quads, located at the front of the thigh) helps to manage the discomfort. Provided there is no inflammation, massage can help tone the quads and also ease the tension in your other leg that has been compensating by the taking extra weight. As with other chronic conditions, Reiki would work in a more subtle way and over a period of time. I've also read recently that wild rosehips from the dogrose contain an anti- inflammatory compound called galactolipid (gopo) which studies have shown reduces pain.
