Legs are swelling on and off, tight calf muscles. Walk dog often, but does not help. Walking is only excerise, but am always gardening, cleaning. I would like to walk more, what can I do to alleviate discomfort and swelling so I can excersie more, walking longer distance. I am 55 and in good health as far as I know. Pulled calf muscle and it seriously hurts to stretch calf area, heard a pop, felt like a ball hit it? Help?
