Hi: I too had similar problems..acute head aches for undiagnosed reasons for six to seven years. These would turn into migraines. Ultimately I tried a herbal treatment and it cured me. Not only me, but so many more have benefitted from it. It is a guaranteed treatment By Grace of God. and to boot it...ultra cheap. There is a herb called "ASTAKHODOS" in subcontinant but readily available in most parts of world. You shall have to check its local name from any Indian friend or a dictionary on herbs.

You should buy appx 250 gms of raw herb. use mallot to slightly  pulverise it. take appx 10 gms (pinch of thumb and two fingers) and put in a glass of water in the morning and drink the water only in the evening. Add water to the same herb (already in the glass) and drink it in the morning. For the next day use fresh pinch of herb. Use it for 15 consecutive days and hopefully you shall be cured. It does cause temporary dryness, so add butter to your diet for the treatment days.

I had relapse after 2 years and again used it. It is now 15 years that I am totally cured. The treatment is side effects free (dryness of skin for few people during treatment only).
