During christmas I ended up getting really sick I had to go into the er 3 times within 5 days. The told me that I had either a viral infection or influenza but they weren't to sure. I started feeling better and a lot of my symptoms went away except for my headache. Now 2 weeks later I got hit really hard again with this illness. I went into the er last night and they said again its either a viral infection or influenza. What do I do? Is there something else going on? Please help me!! Thank you!
