Hi,
Last wednesday, late at night, I stabbed my finger deep with a sharp and dirty object from the garden. Thursday evening, less than 24 hours later, I checked into an emergency to get a tetanus booster. Since it has been very long since my last shot (never done boosters as an adult, I am now 37), the doctor suggested a full course, and gave me the first shot.
After a local pain, mostly on the second day, which waned quickly, things have been slowly taking a turn for worse. It's now almost one whole week later and I seem to have early tetanus symptoms. The arm where I got the vaccine (not the one where I cut myself) hurts when I lift it. It's not a strong pain but it's definitely there, in the upper back of the arm. But more than that I am now beginning to worry because half an hour ago I felt like I was clenching my jaws. I stopped but now I can definitely feel some pressure on the little muscles that clench the jaw, the ones that run very close to the ears, there is even a slight pain. The mobility seems unaffected, but I have read that this is a classic early sign of tetanus, and I am worried that either the vaccine is not working, or it's causing the symptoms itself. Should I worry?
