hi and sorry for ur condition. at the age of 8 my daughter had a little cold and then began to complain that her "eyes are rolling". doctors thought she was having seizures. fortunately, i was told about Cranial Sacral Therapy, which drains fluids that may be putting pressure on the brain. the pressure from ur scuba diving may have done that. they place their fingers lightly over certain spots on the head that help the lymphatic or other fluids drain to relieve the pressure. very gentle and hardly seems to make an impression, but can do a lot of good.
