Head injury, unable to chew, red dot in left eye. Treatment options?

Hey, I fell the other night at a wedding and hit my head very hard, was a bit wobbly after, with instant pain but no visible bump or bruising, I hit my left temple back over my ear. No real headaches as such just a pain in the general area, I knew it was sore but didn t realise how sore until following day when I went to each lunch and started to cry as i couldn t chew! My jaw itself isn t sore but the biting adds to the pain in my temple. The pain has eased slightly which is why I haven t gone to the doctor, but I just noticed a tiny little red dot has come up in my left eye probably nothing but any words of wisdom?
