I would say it's possible that your pain is migraine-related. It could still be something else, or a combination of things.

There are many types of headache/migraine. Some are called "persistent" or "daily", and can either return every day, or be continuous for days/weeks/months.

persistent daily headache migraine

This is why I recommend/suggest a headache/migraine specialist. I had headaches (of a couple varieties) almost daily—some went on for weeks at a time. I went to several neurologists who said they could treat migraine and difficult headaches, but they really didn't know, and were (seemingly) using me as a lab rat/guinea pig. One day while seeing a different doctor on a completely different matter, he asked me if I had seen "the headache guy"—a local neurologist whose practice is just headaches & migraine—he doesn't do/treat anything else. It took several months to get an initial appointment with this doctor, but after hearing my story, he was able to diagnose the exact kind(s) of headaches I was having with just 3 questions. The headaches were/are still difficult to treat, but over the next year I went from having more than 15 headaches per month (the definition of "chronic headache") to less than 8 per month (average 6).

It's not a cure, but it's much better. Now I have medication that works, and I know what to do (and what to avoid).
