I broke my tibia and didn't even realise until nearly a week later when I snapped the ligament in my ankle from lack of support, the doc told me I had a bit of ligament inflammation, took 7 weeks, 2 xrays and a bone scan to find the break and then 3 years later they finally found the ligament. Now 6 years after the original injury I am waiting for my second lot of surgery and I am in pain daily.

So please if you have any doubt get it checked, for me knocking my foot (not even hard) on a bit of wood has caused me endless issues
