Help weird feeling in head.. ending up cant sleep at night...

[typex]

Last night i had a weird experience. until now.  I currently have weird feeling like in the scalp area in my head. ive had this weird lightheaded almost close to euphoria feeling in my head. started last night i was hungry so i ate my dinner and i also drank some soda cola. i ate it and later i had a slight bowel movement in the bathroom. I took bath and i puked a little not much but puked. I later had a weird head sensation like a euphoria feeling in my head. weird. i finished taken a bath and then went on to the computer. Then i ate some sweet cream bits for a while. and some crackers. I use my glasses so i used my glasses and used the computer for a while. My eyes began feeling alit more tiring and head scalp weird feelings. so i lay off the laptop for a while and ended heading a weird like cramp very faint fatigue lightheaded feeling in my head. Especially near my right side ear top area scalp like a weird extreme tired fatigue/sleepy feeling like its pounding away my head.
It felt like i was on drugs or something and i don't do any illegal or un necessary drugs.
i couldn't sleep so i just close the light and my room listened to music. it ***** really bad i had a really weird like cramp/fatigue head/lightheaded/euphoria feeling in my head that cant seem to go away.
i look at the time it goes fast like about 1 o'clock and 2 o'clock i still cant sleep .
i took 1 pill of ibuprofen and waited for a while. my weird head sensation suddenly went away.
but what remands is a weird pounding still cramp/faint/euphoria feeling in my scalp right side near my ear?

help me am i getting a stroke or something?
i somehow managed to get some sleep after taking ibuprofen but still have this weird faint/ pounding head feeling in the right side of my scalp right ear area? and it feels if i am very still or try to be i feel my whole head is just pounding away like it is pulsing. i still feel that weird tired euphoria feeling and its scary and idk?
