Over the past year, I have had several spells of nausea, usually lasting 7-10 days. During this time, I lose my appetite. In February, I had sinus surgery. Since then I have not been the same. My nausea is back and today is day 17 of it. Sometimes it will lessen in the late afternoon or evening. I have had CT of abdomen and blood work done. Both show everything normal. My ENT says everything is good with my inner ear - dispite the ringing in it. I also had an EGD done last summer - normal. Everything seems to be normal, but I still feel the nausea and this time it is hanging around soooo much longer. Any suggestions???
