I have had the following symptoms. -Pain in my lower back -Burning sensation in the stomach and back of my throat -Feeling like I'm about to gag/vomit -Particles of food coming out of my throat and into my mouth -Nausea -Upset stomach -Stomach aches -Headaches -Dizziness -Abnormal bowel movements -Pain in the lower abdomen -Feeling of a lump in my throat -Post nasal drip I have been to an ENT and he says it is not ENT related. My neurologist tries his best to treat my headaches and dizziness. The allergist found out that I am allergic to some weeds, trees, and grass. My regular physician has not clue what it can be. I am a 25 year old female and these symptoms have been affecting me for almost a year. I really wish someone could just tell me why I am having these symptoms. If you have any idea please let me know so I can suggest something to my doctor's.
