On saturday night i fell over a steep embankment onto rock. i had been drinking (just a little...but enough to not pay attention where i was walking at midnight). it all happened so fast so i don't recall hitting my head (but i have a horrible headache), but i can say for certain that i landed very hard on my back and then rolled violently down onto the rocks (right by the river's edge).

last time i became suicidal/in some sort of psychosis; symptoms which took like 8-9 days to manifest. i can't even fathom going through that again. granted last time i was beaten by multiple men in the head with fists and feet.

can you suffer a concussion from tumbling down a steep embankment without hitting your head (i have no lumps...i have a wee bit of pain when i touch top right part of my head...but no lumps)...i do however have a wailing headache that has not let up. also my neck muscles are very sore and my neck is stiff and needs to be cracked constantly. whiplash?

thanks.
