When I was 43, I decided to start jogging in anticipation preventing weight gain (turned out I didn't have to worry about it). After 3 to 6 weeks (can't remember now) my knees started to have pain. I thought it was from the stress & my body would adjust, so I kept running. Soon after that, my knees started swelling up and became puffy. I went to an orthopedist who X-rayed them from about 6 different angles and pronounced that my knees were pretty much worn out and running wasn't appropriate. I quit that, started walking and the problem went away.
About 15 years later, I worked out at a gym lifting weights and exercising on a stair stepper. I noticed after awhile (maybe 2 years) my joints, especially my elbow joints, were hurting afterwards from the weight exercises. I thought it was again just adjustment to the stress. My membership ran out and I didn't renew because I really didn't have time to go faithfully. Soon after that my joints stopped hurting.
I guess the moral of the story is that you should listen to your body. If it is telling you the exercise is injuring you, you should consider changing the type of exercise of reduce the frequency or intensity of it. I can tell you right now when you get into your later years and your body and/or joints hurt almost constantly from over use and stress, you'll be sorry you didn't pay attention to it when your were younger. Plus, Len, just your weight is stressing your joints and associated other parts. I noticed you were attempting to loose some of that weight before. Maybe continuing to focus more on that would be a big help.
