I have multiple Autoimmune diseases and wonder how many of us have multiple dx and what they are. Also, how
many have low vit D and what treatment are you on. And how
many have low neurotransmitters (serotonin, epinephrine, norepinephrine, Dopamine) These when low indicate or lead to low immune system. Since ms is more common in the higher latitudes, vit D is harder to get and it is associated with greater incidence. I have very low D and low Serotonin.
