Hello Sir, Today I was collecting iron nails which spread by my younger brother and during this one nail mistakenly injected in my thumb because the nails are very thin. And even I do not remember how deep it go in my thumb but it does not bleed and does not cause any major injury there is no blood came out from my thumb. Also I want to tell you that I have taken the 2 TETANUS injection in last 3 year. One in december 2016 for immunization purpose and last one in the month of august 2018 in this year (5 months before from now) because of very small cut in my leg. Also I want to tell you that the nail which punctured my thum does not have any blood in its surface and it is not rusted also so PLEASE TELL ME what SHOULD I do. I am thinking too much about it soo please tell me.
