I have a large sore on my big toe. Its been there for two weeks and it has hair growing from it. Its very itchy and it bleeds also. What should I do?

Start with your pcp. There may be an infection or skin lesion that may need to be treated or biopsied.
Need a biopsy. Recommend a biopsy and evaluation as soon as possible.
See podiatrist. Due to the fact the description might possibly be something dangerous it is wise for you to see a podiatrist or dermatologist.
Large sore. Based on the description you should see your podiatrist right away. Don't delay. Good luck.
