I have been experiencing an issue with my knee for months now. There are no tears, etc. just some bone on bone and swelling but I developed a bakers cyst (Swelling behind the knee). Well, I have tried just about everything under the sun, a cortisone shot lasted about 3 days, elevation, ice, heat, etc. and nothing has relieved the pain and swelling.
About one week ago I started elevating my leg at night and icing for 15 mins on, 15 mins off about 4 times per night.
After that, I have been rubbing castor oil directly on my knee and the back of my knee massaging it in. Today, my knee hasn't felt better in months! I highly recommend trying it!
