I have had for over 9 months the come and go with extreme fatigue, frequent headaches, dizziness, nausea, decreased appetite, severe muscle aches and pains, and generalized weakness. I have seen an allergist, neurologist, rheumatologist, and they all say there is nothing wrong with me. I have had lab work for general physical health, inflammatory profile and thyroid testing. All came back normal. Could I have Epstein Barr Virus or Mononucleosis?
