Hello. My Mom pricked her left foot with a rusty nail. She went to the hospital and was given a tetanus shot. They also cleaned the wound and removed a blackish thing. They then gave her antibiotics. But still, the wound has not healed. Around the wound, a sort of lump has formed and is very very hard. We went to the dispensary and they informed us that it s an infection and gave more medicines. They tried to press the wound to remove the puss, but nothing came out. This morning, when I tried to clean the wound, some blood and water came out. Although the lump all around has become a bit soft, that area is still a little bluish. Mom says that the pain has subsided considerably and now, only the wound hurts. I m very worried because I ve heard that if not treated properly, it could lead to amputation of the leg... please advise!
