The swelling could be from weight gain, venous disease, or just getting old. I have all those problems. You get old, fat, and the valves on your arms and legs quit working. You ride, mow, weed eat, and your hands feel like they are vibrating, long after your done. My feet, ankles also swell. My hip occasionally locks up and starts cramping. My neck starts hurting. Go on a low carb diet and exercise. Drink plenty of water. and like everyone says protect your skin, head, ears, eyes...
