It's been more than 2 weeks since the last time i had a Tetanus Immunoglobulin, and a course of Antibiotics for a puncture wound i got from a rusty nail.. But now.. again, i got this break in the skin, not sure if it was from that Spikey metal part of the chair or the metal spike under the chair from the bus i rode on. (I ain't even sure if those metals are rusted or not). This break in the skin didnt bleed and all, but only got this Red look, and stings when i put alchohol. What do i do now?
