I went to the ER last night with double vision, terrible headache, and nausea. They gave me a migraine cocktail with 50mg of benadryl, some Reglan, and some sort of steroid. My headache is miraculously gone still, but my legs are weak and wobbly. I've been having headaches for 4.5 months since I wrecked and hit my head on the dash of my truck and the dr said I probably had a concussion and since I never had treatment for it, it's still happening. No blood on my brain or fractures in my skull though. (Just some background info.) My question is, how long before I can walk and think again? I was in the ER till 5 this morning, I got there at 10:20. I got my IV at about 130 so has anyone had this before and have an idea? They told me I couldn't drive but didn't tell me how long. And they told me not to go to school until next week.
