I exercise 6 days a week (mainly weight lifting). During the past couple of weeks I've added an hour (sometimes more) of walking on a treadmill at a 10-15% incline to my training. This past Thursday the side of my foot started to ache. By Saturday the side of my foot was a little swollen and bruised and walking on it was nearly intolerable. I googled the symptoms and have come up with hyper extension and stress fracture. I don't think stress fracture is a true consideration as it seems to me that even a small break would cause enough pain to prevent any usage of the foot. I was hoping to get others opinions or advice. My copay is ridiculously high and I hate the thought of going to a doctor just to tell me I overworked it. Also, in your opinions, would you stop all lower body workouts or just the treadmill? I do a lot of squatting, lunges, and dead lifting - I hate skipping leg days. Lol!
