Health question from injury, am I okay?

I got hurt last year. An oxygen tank blew up my face. explain: my friend put an oxygen tank in the bonfire and I didn't know. I was close to the fire warming my hands up. When it blew. Afire ball spark hit my cheek. I flew back. Lost my vision and my hearing for two weeks. I couldn't keep anything down and my body and insides hurt so bad. I couldnt move much. My local hospital is stupid. They checked my heartbeat and my ears then sent me home. I had several severe headaches, so i seen the chiropractor he said I hada pinched nerve in my neck. They stopped but now I have sharp stabbing pains in the back of my head. When I get mad, upset, to happy, stressed or to hot, thats when I get tge pain. My doctor says nothing is wrong but won't even check me out? Someone please help. I'm worried.
