Talk to a doctor

I went to a podiatrist last year because I thought I had a stress fracture (it felt like I was walking on a rubber ball), but after being x-rayed I was told it was metatarsalgia and what I was feeling was inflammation. I got some inserts for my shoes, eased up on the running for a bit, and took some ibuprofen. Earlier this year I ran my second marathon and I signed up for my third next spring. Now I only need ibuprofen when it flares up which is mostly when I get to peak running weeks in my training plan. Running is not out of the question but definitely listen to your body when it tries to tell you that you are overdoing it.
