I got a small cut last sunday, the third. I believe what cut me was a piece of a rusty old nail that had been in that barn for a long time. Which means there is a good chance that the nail had manure on it too. Since a few days after that my hand seemed to be achey and at times, like it was swollen. Now, once in awhile it seems as though my whole body feels that way, not constant, as well as some slightly quickened breathing? Could it be tetanus?
