I have been having several odd symptoms for the past two weeks. I have had fatigue the entire time. Nausea a little every now and then. I ve been to my primary and she thought it was mono. I had mono seven months ago. They tested me for it but it was negative. All of my symptoms include: - sore throat - migraines - nausea - diarrhea - green urine (once) - loss of appetite - extreme fatigue - body/ muscle aches - stomach pain All of these are over the coarse of two weeks except the fatigue which has been going on for over 6 months. None of them all at once. Also, I have NOT had any fever during these perdiod. I ve been to the doctor a few times and urgent care once. I m supposed to see an Infectious Disease Specialist next week to see if there s anything else we can do to find out what s going on. I m a 17 year old female. Weigh about 225lbs. Height is 5 5 . I just need to know what could be causing all of this.
