What natural ways are you referring to? I'm 48 and have all kinds of sports related injuries. Left knee operated on 3 times and numerous years abusing my body on the basketball court, so I have some problems with joints.
I take joint relief in the form of Glucosamine and Chondroiten everyday. This has helped quite a lot.
My current weight is 242 lbs. but at one time I weighed 285 lbs. The excess weight caused bone spurs in my heels to just kill me. I had unnatural relief in the form of cortisone shots in my heels. Although the shots gave me relief, they were only a band aid on the real problem. Since losing weight my heels never bother me. I would consider the supplements mentioned above.
Are there specific joints you are having problems with? For example, if your knees are bad, leg extensions are not the greatest exercise. Do you workout?
