I Have A Tempurpedic Bed For Two Years 6000 Dollars

I have a tempurpedic bed for two years 6000 dollars worth of nausea when in bed and headaches for 9 months now could it be my bed? The down size is that I tolorated the comfort because my pain issue regarding my legs went away. Now they will not exchange bed unless there is a belly in it. My belly is in it to be facitious.
