Brief Answer:
Pain due to 
Aleve. Take advised treatment
Detailed Answer:
Hi XXXXXXX 
Thanks for your query.
Firstly, Aleve is an anti-inflammatory pain-killer, which causes severe irritation and acidity in the stomach (called Acute Drug-induced 
Gastritis). Upon that, you had taken double dose of Aleve!
Immediately buy a bottle of 
antacid gel (available OTC) and take 30ml straightaway and thereafter, 30ml every 6 hours for a total of 48 hours. In addition, buy another OTC anti-acid drug, such as Rabeprazole- to be taken twice daily for at least a week, till the stomach ulcers heal. You will be all-right within a maximum of 48 hours.
IN FUTURE, NEVER TAKE MORE THAN ONE ALEVE and should be taken IMMEDIATELY MEALS ONLY: NOT EMPTY STOMACH.
Headache is either due alcohol-induced, 
blunt injury due to fall; or, a 
migraine attack. Take 100mg 
Sumatriptan with a cup of extra-strong coffee. 
	
Consult your doctor and apprise him of my opinion. I am certain that he will agree  with my opinion;  order required tests, and- based on the reports-  will arrive at a certain diagnosis and  prescribe suitable treatment as advised.
Hope I have addressed to your concerns to your complete satisfaction and you find my response helpful and informative. I will be happy to answer further queries, if any.
Fond regards and have a nice day,
