Hello Jeff! Thank you for taking the time to read through my post and give your opinion and advices!
Jeff Grove:
I too have suffered from migraines throughout my adult life but have learn't through the years that for me the way I managed it has decreased the frequency and intensity. I have learn't to know the conditions that trigger them or to identify them early and medicate with over the counter drugs if needed before they progress in intensity.
This is exactly how i use to deal with it.
Being too tired was my main trigger for migraines so i had to bend my life around to avoid the triggers and accommodate the migraines, add the medication, the fear of getting caught off guard (like when driving and having to stop and rest on the side of the road) and it was not much fun.
Jeff Grove:
For me Migraines would be at the top of the worst pain I have had to endure.
yes indeed, this is how we can recognize someone who has had experiences with migraines ;)
I always thought, if i could give my migraine to someone who has never had a migraine before in his life, this person would freak out and call 911 because he would think he would be dying of some aneurysm or something ;)
Jeff Grove:
Pressure may occur but with practice you can learn to recognize any potential for a problem just as you have when doing other activities so there is nothing new to fear. (Of cause speak to your doctor if you have concern). You may find meditation a new tool in the management of your migraines as you have described above. Trust your judgment with this as you are the one who has to live with it.
Like i tried to explain in my first post, this is exactly what i thought was possible to achieve with meditation.
I would have never guess that the migraine would actually completely dissipate and never come back! (somehow i knew it would never come back to, i think i know i could create others, or others that were burried could rise to the surface, but this one would never come back)
I've had a few head aches since but no migraines. and I've been pressing all of my migraines triggers

My doctor who followed me since i was 3 was quite interested... didn't believe me at first.
One of my first memory is to be sitting on a hospital bed when i was 3 or 4 years old, and having a doctor inserting maybe 50 electrodes in my head to somehow try to find the cause of the migraines. (it's like some kind of little nails that he had to push through my skull forcefully, i remember i could hear the sound of the little nail while they were being inserted into my skull)...
Jeff Grove:
You hear stories such as Mahatma Ghandi at age 77 having an appendix operation with no anesthetic. During the operation he held a conversation as if the stimulus of pain was not even there. He said that you are truly free when your wisdom guides every reaction, including those reactions you thought were impossible.
I can understand this, that moment when i was sitting and i truly let go of wanting to control the "electric worm" migraine, of truly let go of trying to prevent it growing and killing me, i could the simply observe it (it was kind of beatifull looking back).
It was as intense as possible but it was no more pain, it was just energy. It could have engulfed my whole body and destroy my body and it would not have bother me the least.
At that moment i could have set fire to myself and be able to simply observe without being afraid...
Jeff Grove:
You stated this was your first retreat, set the pace that works for you, experiment, there is an opportunity to gain further insight into a physical process.
Investigating the source of the pain will reveal the impermanent nature of the sensations or vibrations, the aversion to the experience.
Another method that helped was to softly focus my attention on the dantein area (just below the belly button) and this relieved the pressure in the head, as energy/Qi follows intent.
Tonglen is another technique of accepting the pain, taking it in and transforming it.
thank you for these advices!
During this last year i searched for people who had a similar experience and found that Ajahn Brahm was describing something very similar with his tooth ache.
