I have been running a lot and recently started to have lower calf pain. when i walk around or ice, i can sometimes feel the pain shoot down into my heel/foot. i assume its a strain and rest is best, but wanted to make sure it might not be serious?

Not sure what “running around a lot” actual means. You would b best to be evaluated by your family doctor. They can determine the type of Referal you might require. A podiatrist the swelling from running could be placing pressure on your nerves. But. I Am more concern about why are your calves are swelling. Bilateral calve swelling with running is not normal. Further evaluation is needed
