Bathing and migraine

[evankoum]

Even I'm suffering from migraine for 40 years few years ago I understood that one (maybe the key) trigger is the bathing (shower).
No one of my attendant neurologists accept it, but after taking away one by one the suspect factors and focusing on bathing, I understood that with no doubt it cause me migraine (less in summertime).
I have tried decreasing the frequency of bathing to 2-3 times per week as well as to stay for a whole week with no bath (and no migraine). For years I stopped bathing in the morning (only in the night) and I always practice a careful process, drying my neck and hairs and staying home with a hood on my head and neck. Unfortunately it does not function in most of the cases and 6-15 hours later my migraine appears.
Someone suggested using hair shampoo without sulfate. I tried neutral soap, but with no any improvement.
Few years ago I had a short period of some relieve with acupuncture.
I cannot understand if it is a muscular, or vascular, or nervous, or vertebral problem in neck or head.
Any advice or suggestion?

High humidity could be a trigger. I have also migraines with wet weather. I'll focus on that trying to avoid high humidity.

I don't know if you have access to cigar shops in Greece but most have walk-in humidors.  These humidors have high humidity to keep cigars fresh.  By going into a humidor you can confirm whether the same trigger is causing your headaches or migraines since you would be recreating the same high humidity environment as your shower.  At least this will help you determine if this is truly a trigger.  

Some individuals are susceptible to unusual triggers and it would not surprise me if humidity could affect you.
