As I was reaching into fridge, I came up and hit top of head on freezer door that had opened. It was a hard blow to the head. I was a bit light-heading and not completely with it, but I knew exactly what I did. Next day, I slurred a bit in the morning, but that was it. Since the incident, I have been very sleepy, and my head hurts badly, I do sometimes get sharp pains. This happened 9 days ago, and I went to E.R. 3 days ago. They x-rayed by skull and discharged me. I do not have an appt. with dr. until 3/20. My temp. is lower than normal (temp. is 97.0-usual is 98.6 give her take a little) Should I return to E.R. or is it normal to feel pressure and have headaches all over? Do I just wait on appt.?
