I have all the reasons that my lifelong incidents and symptoms point to acute porphyria.

The incidents started when I was in my late 20's... My mother had the same symptoms and was never diagnosed.
About four times a year I'm stricken with cold sweat, stomach cramps, nausea and loose bowel movement, simultaneous. Immediately, after, laying on the cool floor helps me restore to some normalcy. Then I am as weak as a kitten. My strength is slowly restored after laying down and napping. With in hours I feel my normal self. The attacks come on suddenly, causing me some embarrasing time. as a precaution I keep plastic bags in my home bathrooms. I have dealt with this for 6 decades and now my daughter is experiencing the first of the symptoms, weakness with the need to lie down till it passes. Can a general Physician get the urine tests and readings that are necessary for diagnosis? Is there anyone who can share their experience. Because of the rareness of proyphyria, physicians have never paid attention except to once calling it a panic attack.
