How common is simply a mild pain?

From the ages of 3 up to about 20, I suffered from episodic migraines without aura. Essentially, about once a fortnight I would develop a pretty intense pain behind (usually) my right eye and it would last until I went to sleep. There were no other symptoms at all, and the pain itself would be gone when I woke up. Note that the pain was not throbbing or pulsating, but constant. The main causes for these were too much screen or sun, not enough food or water.

Then, at the age of around 20/21, I developed chronic migraines. These migraines were similar to the episodes I had had growing up (a similar feeling and location of pain, and with no other symptoms) but would be much milder (the sort of pain I can go about my day with) and just much more frequent (at times, they are most days). This time though, there seems to be no immediate cause. For example, even on days where I look at little to no screen or sunlight, and eat and drink well - I still get one. Occasionally (about once every 3 weeks) one of these chronic migraines will turn into a bad episode (essentially the pain will increase to the point that I have to go bed).

I have tried most treatments through the NHS and found little to no luck (botox, beta blockers, sumatriptan).

From reading posts on this forum, and indeed speaking to people over many years (I am now 26), I have never really come across sufferers with the same symptoms as me. The pain is usually mild, non-pulsating and not accompanied by any other symptoms at all.

Does anyone have a similar case to me or have heard of one?
Any suggestions for treatments?

I would be really grateful to hear😀
