I fell and cut my left side of my head about three four inches right about near the pariernal bone area. The center of gash was the deepest and I bleed heavyly, but applied pressure until it stopped. My head throbbed for days, I had headaches, but it subsided. That was about two months ago, however I do expereience throbbing and it has become increasingly more on each day. I had headaches to the point my left eye feels swollen, at times I am nauseous, but I will take headache pills, and sleep it off, but the next day it will start up, but more so by late afternoon I feel the throbbing pain on my head down to my left eye to my left ear. I find that at times, when I rest my body reacts like I am having a mild seisure. I hit my head against the post base outside my front porch. I am schedule for an MRI, but not sure what to expect.
