Take it seriously is what I say – go see a specialist and get an X-ray to make sure it’s not fractured. If you can wear an airboot for a couple of weeks then do so.
I didn’t after my feet swelled in an ultra distance cycling race – putting pressure on the ball of my foot. I carried on riding and when I got home largely ignored it – I ended up with a necrose sesamoid which causes me lots of **** pain and headache in the long run. If I had rested in the months after the original injury I would have probably been fine.
I’m avoiding surgery to have it removed for now as I fight the arthritis train in the rest of my body.
Take is as a lesson that you are doing something wrong to your feet – look at the shape of your shoes and your feet in general. Altra shoes are your friend – start looking at how much control you have of your big toe… go see a special podiatrist who believes in barefoot techniques and making your feet strong.
