Hi, I got poked by a stapler pin recently at a function on the foot. I was able to take out the pin almost instantly with a tiny droplet of blood and felt a tiny pinch. Now after few days I still feel pain while walking and cannot completely apply pressure. I see no physical evidence of puncture or injury or puss or a swelling. The pain exists only if I exert pressure. Please advice if I should take a tetanus or consult a specialist on the matter. Thank you!
