Thank you for posting your query at DoctorSpring.com
I have noted your symptoms and would like to reassure you that you do not have any serious problem.
It is most likely a migraine type headache episode, which has a tendency to get exacerbated with strong smells. You should take a medicine such as naproxen or rizatriptan for pain relief. You would be fine in a few hours.
