8 weeks ago i got a bang to the head while playing sports.i did not pass out. i got a hard bang to the left of my head and face.the left of my jaw turned black that day.ever since ive had a headacke,its not bad but dull and never goes away even with pain killers.i have pain in my left temple and my jaw is still sore,also my left ear hurts,,my jaw feels tight. the worse thing is i constantly feel as if ive had a few drinks!! i dont feel right,i cant even drive as i cant think properly,im slow to react and i feel slow,if you know what i mean! also a few times a day i will fall to the side as i lose balance like the ground is moveing.i am so tired all the time. i have not gone to the doctor yet, i think he will probly send me to the er and i dont want to go if theres nothing wrong. does this sound familier to anyone? do you know if it will go away on its own over time or should i worry. thank for replies
