Does no pmo cause migraine?

Actually, there is a huge connection between ocular and other type Migraines associated with Porn.
In fact a porn users brain scan can show evidence of a Migraine most in Porn users is Ocular and what are called body Migrains which can cause weakness in arms and legs as well as numbness and lack of some muscle control, this is seen more often in cronic porn users who have done so a long long time,

 

Depends often on ones past as well, drug use and other addictions can also effect this even if in ones past.
If persistent in strength I would go see a doctor as it could be a sign of other illnesses.

 

Orgasms release a few interesting neurochemicals in the body through different parts of the brain and adrenal gland, mostly. A couple of them are anti-inflammatory compounds (which are able to reduce inflammatory reactions such as those caused by fatigue and stress) and immunoboosters (which reinforce your immune system temporarily). I suffer from chronic headaches/migraines (depending on the type the effects are different and so is my day...) and I used to PMO to get relief through these neurochemicals. One more thing that kept me under even at times when I wasn't horny or anything. Headache -> PMO to get better. And then, you guessed it, when the compounds wear out after a day or two, the inflammatory symptoms causing my headache are still there, because all I did was get a high to cover them (i.e. medicated myself), and didn't treat the lack of sleep/excess of work that were causing it
