I have an unofficial SPD diagnosis from an OT in 2010. No one in my state does adult diagnoses. I have now also been diagnosed as being at-risk for developing MS. I'm currently having a whole host of pain symptoms that the Dr says are unrelated to the MS risk.
How do I advocate for myself knowing that the SPD makes me present differently neurologically anyway?
I've missed two days of work in 2 weeks, which is a lot being a teacher. Any advice would be appreciated.

I'd recommend you check out the Feingold Diet at Feingold.org. Many pain symptoms are related to food additives. Regarding your MS risk, do you take Vitamin D3? Vitamin D therapy is a common treatment for MS, and beginning it now may delay the onset. Perhaps ask your Dr about it and research it on the web as well. Many, many people are Vit D deficient, especially those living anywhere north of Atlanta.

Does having SPD put you at higher risk for MS? Or are they unrelated?
