I am a 24 year old female. When I was about 9 yrs old a horse stepped on my right foot. I had no trouble walking on it afterwards. So I was never taken for it to be checked out. Just this past week I started getting moderate pain in the same spot that was stepped on. The pain goes from the big toe to the third toe in. If I am at rest the pain dulls but as I put pressure or walk on it the pain comes back. Any ideas on what could be the cause?
