What are the symptoms you get when you have tetanus(lockjaw)?

I'm 18 right now about a week and a half ago, my finger got stuck by a fishing hook outside. It didn't even draw blood so I didn't think anything about it until now. I was reading up on symptoms of tetanus and it seems that you get painful muscle spasms and such but I don't have any muscle spasms and no pain but I did read that other symptoms are loss of apetite and irritability which I do have but others which I don't (fever, headache, and more)

i first got worried when my jaw was a little stiff yesterday.

I have been vaccinated against tetanus but I don't know when the last time I got a booster shot was. I remember getting a shot when I was maybe 14 or 15 but I don't know if it was a tetanus booster or not.

If anything is worse i'm going to the doctor tomorrow.
