Important: It sounds like you need a tetanus shot, if its been 10 yrs or more since your last one. The best otc cream is Hydrocortisone for inflammation.

Tetanus Vaccine: Tetanus vaccine is very important in all punctured wounds that especially involved with metals. Tetanus bacteria are commonly in soil, dust, water, and manure. But you are more likely to get tetanus through deep punctures from wounds created by nails. The bacteria travels via blood or nerves to affect your central nervous system. Better be safe than sorry.
