Thank you for posting your query.
I have noted your symptoms. Based on the description, the most likely diagnosis is acute migraine attack.
In migraine, you can get severe headaches along with nausea or dizziness. Symptoms tend to get aggravated with exposure to sunlight or loud noise.
As of now, you can take medications to relieve your symptoms. These include rizatriptan
tablets for relief from headache and betahistine
tablets for relief from dizziness.
If headache recurs later at increased frequency, you can also start preventive medications such as Topiramate
to reduce the severity and duration of headache episodes.
I hope it helps.
