Thanks, Lissa for the interesting survey. I checked that I never had a viral infection, but I remembered that 10 years ( 1988) before the injury I had a very weird virus and was very sick. Had hives even from wrist watch pressure. Developed severe sulfite allergy. Got terrible asthma, some fatigue, severe sinus problems, chronic throat clearing, more. - symptoms lasted nearly a year. This virus reoccurred each October, but lessened over about 5 years. So, I am really confused now.
