I had been doing so well.

Then today I twisted wrong, and searing pain ripped through my ribcage so intensely that I thought I was going to pass out. It died out after a couple hours, but now I'm more than a little worried that I've done something to set back the healing process.

Guess there's just no easy recovery from getting hit by a car.

And on that note...

Ever since getting a tetanus shot, I've been a little on edge.

Sometimes when I'm chewing it will feel like my jaw is tightening up, and I start to wonder if the vaccine didn't work and I've contracted lockjaw. Then that's about all I can think about for hours.

But the bigger issue is the vaccine itself. From Wikipedia...

Tetanus vaccine is a vaccine composed of deactivated tetanus toxins. This vaccine is immunogenic but not pathogenic and is used to prevent an individual from contracting tetanus.

And that's not all...

The type of vaccination for this disease is called artificial active immunity. This type of immunity is generated when a dead or weakened version of the disease enters the body causing an immune response which includes the production of antibodies. This is beneficial to the body because this means that if the disease is ever introduced into the body, the immune system will recognize the antigen and produce antibodies more rapidly.

What if they accidentally shot me up with LIVE tetanus toxins instead of deactivated ones? That wouldn't be a good thing, now would it? This would certainly explain why my jaw keeps feeling like it's tightening up!

If you don't hear from me again, I'm probably dead.

After writhing in agony for hours.
