My Stomach Is Upset All The Time, Food Does Not

My stomach is upset all the time, food does not taste good to me and that includes food I use to love. Once I have eaten some food I feel like throwing it up. In February I came down with a septic infection that sent me to the hospital for over six weeks. It was caused by a boil that was infected lanced and got into my blood stream and possibly bones. I am still in recovery but the infection is gone. I continue to take anti biotics.
