Hi, I have been feeling poorly for the past week. The two things that were going on are I had the Flu for three days. And prior to my getting the Flu I started taking a new medicine called, Furosemide 20 mg. now my symptoms have been, pain in stomach area middle to upper part of back pain, some vomiting and a sence of being light headed and sort of in a fog. A moderate case of dehydration . I did not take this medicine today and have been feeling better by the end of day. Also a loss of apatite in three days I only had one meal. And the rest of the time I ate a piece of fruit, fruit frappe crackers. I think my problem was the medicine. Look forward to your opinion. Miss May Churchill
