M.L.Berg, sorry to hear of your sewage back-up problem.
Question #1:
>I have been feeling very nauseated this past week and headaches, do you think it is caused by this?<
My Answer:
It very well could be, or you may have a touch of the flu, a cold, or you may be suffering from the effects of PMS, or you may be pregnant. :>) Consult with a physician.
Question #2:
>Also, How soon should I have it repaired?<
My Answer:
Immediately!!!
In addition to the noxious odors from the sewage, disease organisms like viruses, and bacteria are in the sewage, and these critters pose a health threat to you and your family if proper disposal is not provided. JWA
