I run 1.5 miles everyday or every other day. (I'm preparing for a physical agility test that is 1.5 miles in 14 minutes 49 seconds) When it comes to running you have to listen to your body. When I started running my hips and calves would kill me. I figured out that I needed to start off slow and short. I also did research into how to run. Most adults run by putting their heel down first. The proper way is to land on the ball of your foot then your heel. Do a search on youtube. It sounds really weird but I found it helped a lot with the pain. That and new sneakers.
Actually the best way that it was described to me on how to run is to look at a 3-4 year old run. They usually run on the balls of their feet. It was very interesting.
But like others have said listen to your body. If you don't you could risk injury, such as a stress fracture, and could be off running for awhile.
Good luck with everything!
