HPV vaccine Fainted and shaking

I had a tetanus booster vaccine yesterday, and got a HPV vaccine today.

When the nurse injected the hpv vaccine needle, it hurt more than usual. I think 2 seconds later I went unconscious, but I am not sure if I was unconscious, I think I was shaking the whole time, I was dreaming like you would on a fever, jumping from one thought to another.

Then I managed to open my eyes, all the clinic was there, I stopped shaking a few seconds later, then they layed me down and they put my legs up and that got me feeling better. 5 minutes later I was feeling better with a mild headache, so I went home. I am now better but looking back on the morning, it was really weird.

I never fainted before so I don’t know if I should be concerned, although the doctor said it was okay. Just wanted to share this, it is probably all good, now that I am feeling better.
