Is slight wound discoloration an early symptom of tetanus?

[Zac M]

Today I was doing something admittedly rather dense and scraping my name and address off of a medicine bottle from the pharmacy (for reasons which you would understand if you lived in my area) with a pair of scissors. I was scraping the in the opposite direction that I should have been—towards my hand, and of course I inevitably nicked myself rather well and took a fairly substantial chunk of epidermis out of my index finger. The chunk was not deep, but it did cause significant bleeding, as open wounds tend to do. I sterilized it immediately with some antibacterial dish soap and witch-hazel, then wrapped a band-aid around it and continued about my business. However, because when involved in any sort of activity in which requires the use of the hands, one has the tendency to frequently bend the fingers, so it continued to bleed through the bandage for quite some time. After I finally got around to changing it, I noticed that the area around the wound was slightly off color—a golden-grey. It was then that I began to wonder if this was indeed going to be a much more serious circumstance than I previously anticipated—and upon deep contemplation in which I searched the corners of my memory for the last time I was inoculated for tetanus, I resolved that the most recent time I had done so was about 8-9 years ago when I was still in middle school. I know that the suggested limit between inoculations is about 10 years, but because I am unsure whether or not my prior assumption is correct, due to a hazy memory, the subject is a cause of some concern to me. I was wondering if anyone is familiar with tetanus and early symptoms who could either validate or content the possibility of my contraction of this rather terrifying ailment. Please do tell me of first-hand experience or point me to a specific source which rather than leading me to a general webpage with arbitrary information for me to sift through, as I have already searched the internet myself and am more than capable of reading wikipedia’s page on ‘Tetanus.’ Thank you for any help you may be able to provide!
