Concussion/Aneurysm?

[kayley4]

Im an 18 year old, female. Since yesterday (Friday Jan. 3), I have had the worst headache I have ever had. On the left side of my head, there is shooting pains that will come and go every 10 minutes or sometimes longer. Usually lasting only 5 seconds or so. As for today, the headache has not went away. It is a little above my eye. Also, my left side of my neck is really stiff and sore. Half the time, my whole body hurts, and I feel really tired all the time. I got hit in the head really hard Wednesday night and I don't know if I have a concussion or something else. I also wanted to know if you could get an Aneurysm from getting hit in the head? I looked up the symptoms for both Concussion and Aneurysm and they both have me concerned. I haven't made it to the doctor yet so Im getting scared because it is all getting worse. I just would like to know what it sounds like so I could be a little more at ease. Please and thank you!

Im new at this so I really don't have a clue what I am doing, sorry! But I forgot to write that another problem im having is I feel sick to my stomach. I haven't thrown up or anything I just don't feel right.
