I am a mental health provider that works in medical settings. I suffered with a marked case of visual snow after
a sudden onset of neurological illness, that slowly improved over a 3 year period. It is now about 10% of it's
former severity. I believe in my case it was associated with overexpressed immune response--allergies and possible
exposure to toxic black mold at my work site. Improvement followed addressing severe Vitamin D deficiency (with
symptoms), allergy injections weekly for 5 years, and change of work site. I still have tinnitus, some trails and occasional
symptom flares, but the condition is very manageable. I am interested to see if genetics plays a role in this condition.
