I have been dealing with IgA deficiency for about 20 years.
My symptoms include bad sinus headaches, a lack of energy, and lessened cognition or brain fog.
I can go into what I have learned to do to treat it if you are interested and I would prefer to hear your symptoms first.
I would also like to hear what is working for others to help give some semblance of a more normal life.
Love and blessing,
Reuel
