Lower inner leg pain

I am having some bad inner leg pain above my ankle and was wondering what might be causing this. I have just bought some new running shoes hopping that it would go away. I’m not running my only around 3 miles every other day and other cardio the rest of the time. Is this something to be worried about? I’ve taken a week off of running and went back to it to get the same results. This just started about a 3 weeks ago. Any help would be great… I do stretch before i run the same as i always have.
