What Causes Tongue, Eyes And Stomach Pain After Being Bitten By Mosquitoes?

I just got back home from Louisiana. There I was pretty much eaten alive by mosquitos, I had a really bad road rash that was unexplained, I felt and seen squiggly lines on my skin. And now I feel something(s) moving around in my head. There is pain in my eyes, my stomach hurts, my tongue hurts. There is pressure below my ears, and my blood has a metallic oily color to it. I m not sure what s going on. I ve been to the hospital a few times, CT scans were neg. But there is something there I know it. I can feel them moving! Someone please help me!
