Hi.
I've gone through your query. I can understand your anxiety. 
Your symptoms might be due to Classic Migraines with pain radiating to eyes & jaw & vertigo (
dizziness). 
Migraine headache presents with  Nausea, vomiting, 
stomach upset, dizziness etc. I advice you to, 
1. take Analgesics like Naproxen /
paracetamol & Triptans
2. Tab. Vertigon 16 mg twice a day 
3. 
Neck massage, Relaxation & Stretching exercises. 
4. YOGA 
5.  Have Caffeine drinks 
6. Avoid exposure to light, noise etc 
7. Avoid excessive salt and water
8. Avoid jerky movements.
Hope I have answered your query. Let me know if I can assist you further. Get well soon.
