I think i may have a stress fracture in my left foot. Had mild pain when it is bearing weight since yesterday, with that pain getting much worse when attempting to run this morning. I stopped running as the pain was telling me there was something not right at all. This was about an hour ago, the pain is now a dull ache at rest and a sharp pain when walking on it. Should i get it properly diagnosed, or just rest it myself and do low impact stuff for a few weeks. If it is a stress fracture and it gets diagnosed, will it cause problems for me down the line at the Medical stage?
