I have borne six children, many years before the MS diagnosis however. I wish my children could be followed in a genetic study - they are from two fathers, two marriages, and seemingly ideal subjects to look for a maternal genetic factor in MS.
I have had one MS "hugs" attack and it is excruciatingly painful.
Something is secreted during pregnancy which relaxes ligaments and muscles to facilitate the obvious huge expansion of the uterus and pelvic structures. I got uterine ligament cramps that were disabling and soreness that took days to go away, and all muscles would be more prone to feeling effects of sudden overuse or pulling injury when I was pregnant. I am not sure, but would not the WBC count rise with injury as well as infection?
I wonder if anyone mentioned the term costochondritis during your stay as a possibility.
Now, at age 52, my MS lesions are in my neck on MRI. I envision my neck as a slow progressive obstacle course for nerve impulses to navigate back and forth and a percentage of impulses are messed up. Other than someone having a voodoo doll on me, what else could explain sudden stabbing pain in an area where there is no injury or overuse and which disappears as suddenly as it began?
