I've been much more active , walking a lot and staying long standing . I have a sore knee , ankle, in the lower back and my leg is swelling , what could be the cause ? I've been walking and keeping standing much longer than usual, and I have also been on uneven surfaces. I am overweight.
Many people often feel sore and experience more pain when they start exercising, especially if you are in bad shape. Chances are you have arthritis that is causing joint and back pain. I recommend you increase your physical activity gradually and to fixate on what your body tells you. Your GP, physiotherapist or physical trainer can help him.
