wide arteries, coital cephalgia

[Johnnywhee]

Several (2) years ago I had some chest pressure and was referred to a cardiologist who tested me and referred me for a catheterization, expecting to have to stent. According to the cardiologist, my tests suggested two completely blocked arteries. Instead, I was told I was ok and that my arteries were wider than normal. That was it. Since the pressure woke me up at night, the event may have been caused by my sleep apnea (yes, I use CPAP).

I've since developed high blood pressure and am on an ACE inhibitor. I also take other drugs, as I have developed metabolic syndrome in the past year (high triglycerides and cholesterol, Type 2 diabetes). I've recently had some trouble breathing (but I do smoke in moderation), as well as some pain in my left leg. In fact, it's not unusual for me to have pain or tingling in my shoulders and left arm when I sneeze (strange - perhaps a neck issue). What's bothering me most at the moment is coital cephalgia, and I wonder how if at all it may be connected to my other health issues.

Two days ago I experienced extreme pain in the back of my neck just prior to orgasm. While the pain has subsided for the most part, it has taken two days and painkillers to do so, and I had to cease sexual activity this evening as I could feel it beginning to happen again. I am now nauseated and have a headache, surfing the web for answers (and no, I don't take any meds for ED). This has happened several times before in the past, but not often, and has never held on so long.

I'm overweight (BMI - 32) and find it difficult to exercise, as I become winded quickly.

I just turned 44, have a family history of high blood pressure. Maternal grandfather suffered from multiple aneurisms, and one eventually killed him. Maternal Grandmother died of heart failure (though both lived past average life expectancy). Maternal uncle developed metabolic syndrome. No other known family history. Paternal relatives don't tend to die of natural causes.

So, my questions are:
1. Are larger than normal arteries a health issue or risk, and why would they cause me to fail my cardiac exams and prompt a catheterization?
2. Is coital cephalgia related to heart disease?

Thank you for your time and trouble.

Coital cephalgia is caused by the deficiency of the nervous transmitters acetylcholine and serotonin and the hormone DHEA and testosterone/estrogen in the brain. It affects the rear brain and the Cranial (parasympathetic) Outflow Nerves.
These headaches are benign in nature and are rarely associated with any significant health problem. Most sufferers report that symptoms disappear within a month of onset.
