You might find this helpful - it's an article about
MCAD and in table 5 in the article, it gives treatment options:
www.ncbi.nlm.nih.gov/pmc/articles/PMC3069946/It also has a listing of differential diagnoses, which may help you explore other possible issues, or rule them out.
I have been using one of the meds often used in MCAD and it's been pretty helpful. It's Quercetin. Only I take it at low levels since it helps not only with inflammation, but digestion and can be overused.
