Our experience with our son was that he was sensitive to many things which worsened or created new symptoms. These included catching a virus, food sensitivities, stress and low pressure systems. Any problem with sleep and of course significant exertion were problematic too. He did not seem to have light sensitivity or smell issues, but I have heard others do.
Sorry for the delay in response. I have been very busy with things.
His initial symptoms were Headache, Loss of part of his vision (sometimes left and sometimes right), brain fog, sleeping 15-16 hours per day.
As time passed the headaches and vision loss became less and the fatigue and brain fog as well as irritability were more prominent.
He also occasionally had other issues including unusual pains in his legs, nausea/vomiting, indigestion, severe sinus congestion and hives. The most scary incident was when he went into Anaphylaxis in the Doctor's office when they were doing routine allergy testing on his skin.
Toward the 5th year prior to treatment, his symptoms were predominantly the fatigue, brain fog and irritability.
