I have dealt with Fibro for over 20 years. Ive had gut problems since I was 5 - chronic constipation (I maybe went once a week) - and then in my 30s it changed to the opposite and was diagnosed with UC. When I was diagnosed with Fibro it was by a visiting Dr as the Drs where I was didnt believe fibro was a think. It was nice to know I was not imagining things. I was diagnosed with symptoms and the trigger point test - 18 clusters of nerves on your neck, back and butt. If more then 12 are inflamed at the same time they say you have it. I had a very bad car accident with horizontal and vertical whiplash and they said that trauma may have kick started it.
I think if anyone has an over active immune system then it makes sense to have multiple issues. While the bur removal cures UC that doest stop your immune system from continuing to pump overtime. I have a lot of friends in my life who have auto-immunue issues and they all have multiple issues - not just one.
Which came first? who knows. I had jaw surgery when I was 16 and they left some hinges in on the bone that were to slowly dissolve as my jaw healed. Did that foreign body cause my immune system to start pumping? My BFF got breast implants and within a year had to have them removed and now has multiple immune system issues - was it the foreign body that started her off? who knows
