Someone please help

In need of advice, answers, or direction to where I can find answers please

Back in 2013 I fell on my head and a bolt sticking out of a pipe hit me straight on my eyebrow

I had to get stitches and it healed fine

However, I did have tenderness in my nerves (if that makes sense?) Going from my eyebrow to the top of my head. It's been yearrrrssss now and occasionally it will still bother me. And at times there will be a very tender spot on the top of my head that feels like a bruise that I cant describe but it's so uncomfortable when I put my hair up the hairs in that area pull and cause weird pain...

I know it's such a hard question to answer especially on here but I'm at least looking for someone to direct me to someone I can ask...
