Why are My Headaches Not Going Away Other Symptoms as well.?

Im 17 and usually in good health up until 2-3 weeks ago when i woke up around 1am complaining of a headache.I was given ibuprofen ti ease the pain.Well not long after i had taken the ibuprofen i started vomiting and i could not stop vomiting while having a throbbing migraine. I Ended Up in the ER because i was throwing up so much i became dehydrated and had to have a CT scan. Fortunately nothing showed up on the CT scan and i was told i had a bad headache and to stay on a liquid diet for 2-3 days. They Did not prescribe anything and also told me to take ibuprofen for the pain and also to see a neurologist.

About 2 days after that had happen i was still having headaches not as severe but still quite painful and my muscles in my legs,arms,and now face and hands have this tingling sensation that will not go away. I saw my primary doctor last thursday and told me that i had no tumor,meningitis or aneurysm. So He Prescribed me 3 different medications they are as follow: Gabapentin,Mobic and Caffeine pills
The Gabapentin is for the nerves and the other 2 are for the headaches.

what is really bothering me the past couple days my neck and spine have been aching alot and i have been taking ibuprofen and nothing seems to help.

I have only been on the medication for a week and realize it takes time , im just worried thats all.

Oh and One more thing . I am getting blood work done tomorrow to rule out Diabetes and Multiple Sclerosis.

I Realize nobody on Yahoo Answers is a Doctor.

oh and the reason i didn’t see the doctor right away was because they were booked solid that week ( the week i started having all of this trouble) and had to wait the following week.
I will let the doctor know when i go . thank you. :]
