Suggest Treatment For Severe Neck Pain And Dizziness

I have scoliosis and a slipped disk, I did something to both of my shoulders after ramming them into the door frame on accident, I had something happen to my neck after my car accident due to bad conditions, and now, I feel a lot of pain to the point it ll make me weak to move, and when I crack them or stretch to release the pain, I get this metal/ blood taste in my mouth and I can also literally feel my bones grinding against each other. It makes me get dizzy as well, to the point I ve blacked out a few times. Woke up to finding my head hitting the toilet. Is this something deeply concerning or am I just freaking out?
