about 5 months ago I was beat up & knocked unconscious, when I came to I had blood running down the top of my head as I was laying down. I had a cut on my left side of my forehead starting in the eyebrow area & going up to about the middle of my forehead. Lately I have noticed when my sinus s or allergies are acting up my forehead seems to be more senitive. I have also noticed I have been having some shooting sharp pains on the left side of my head about the temple area. I noticed that the scar hurts in cold weather & when the wind is blowing hard (like i think I may have a nerve exposed). It hurts to squint in the sun or to raiser my eye brows . I didn t go to Dr, even though I probably needed stitches, I used to be a med aide so once i got the bleeding to stop I used stery streps to close the wound. I didn t go to Dr because I was embarassed, I wear hats now to hide my scar Do I need to be conscerned about these symptoms or occurances?
