Hello Rsahilv,
Welcome to our Pain Management Community. I'm glad you found us and took the time to post - but sorry to hear about your headaches/migraine. Sorry, I am not certain I understood your post completely. Please feel free to add more information - or explain your question(s).
Please know that you are always welcome here. However I'd be amiss if I didn't inform you of our Migraine and Headache Forum. It's more focused on issues such as yours and may offer more suggestions and information. Here's the link:

Are you asking for the definition of a Migraine? Think of Migraines as a severe Headache. Often the two terms are used interchangeably - but there is a difference. Headaches are unpleasant pains in your head that can cause pressure and aching. They can range from mild to moderate pain and usually occur on both sides of your head. However Cluster headaches occur on one side of the head, but aren’t as severe as migraines. When you talk about Headaches and Migraines it gets complicated and detailed. I won't bore you with a lot of information.
There are all types of Migraines and Headaches. Here's a list of some of the terms used for Migraines. Stress Migraine, Abdominal Migraine, Silent, or Acephalgic, Migraine, Sinus Migraine, Ocular Migraine, Seasonal (Allergy) Migraines, Cyclic Migraine Syndrome, Gastric Stasis Migraine and Tension Migraine. And there are more!
Migraines are DX (diagnosed) based on one's specific SXs (symptom)s. It comes with more SX that just head pain. As an example I always have nausea and vomiting when I have a migraine and I cannot tolerate light. They usually affect only one side of the head - but can affect both sides.
If you have no other SX and your pain is bilateral (both sides) than it sounds more like a nasty headache. There are Headache and Migraine Centers and/or Physicians that specialize in the treatment of Headaches and Migraines. If you are obtaining no pain relief or reasons from your current Medical Practitioner than it may be time to consult the specialists.
I'd use your Search Engine to locate information on Migraines and Headaches. There is a lot of information available. You may even be able to find a Practitioner that specializes in them in your area.
I wish you the best and hope you'll keep in touch. I hope something I have said has been helpful. If you need more clarification or you have specific questions please feel free to ask.
Take Care,
