I also have constant sinus allergies etc, from not sure what, but I think there may be a chemical link. I also get migranes and I have noticed they can be triggered by flurescant light, fumes from paint or cars etc. I often seem to get a virus that I find hard to get rid of and I think the building I work in (rundown)is having some effect on my health. I have heard of renovating and the problems you have talked about. Sometimes it's lead, mercury etc in paint or other chemicals. I am trying to learn more about all. Let me know how your going.
23rd July 03, ADR c5/6
Also disc bulges c3/4 and 6/7. Numerous facet and nerve blocks along with extensive conservative treatment prior to surgery.
