Hello Sir, I have been suffering from dysautonomia related symptoms since few years and I am taking treatment from a neurologist. The treatment is symptomatic and I don't see any real benefits. Recently I have joined a facebook group called Dysautonomia that is run by Dysautonomia International Organisation. Some of the people who are part of the group said that "Mast Cell Activation Syndrome" can cause Dysautonomia. I have tested IGE levels and it's showing HIGH. My dysautonomia symptoms increase after eating food especially after eating outside food. From childhood I have chronic bronchitis and nasal congestion. Sometimes when I scratch my skin I get red rashes on thighs and arms. Is high IGE causing my dysautonomia? I have already tried Montelukast and anti histamine, but I didn't see any benefits. I also have sjogrens syndroms and I'm taking treatment from a rheumatologist. Are there any Allergist, Immunologist or any relevant doctor in this platform? I would like to consult.
