I had a strange, nagging pain at the base of my head July 2013 for about 2 weeks. I went to see a doctor. I was diagnosed with Hypertension & given several medications. The meds didn't seem to work. I then developed the WORST headache ever. After 2 ER visits & 3 doctor visits, I was told I had what sounded like VM. It was "unofficially" confirmed after 3 other cases in the area. I was told since it was viral, there was nothing much I could do. Just rest & take OTC Ibuprofen/Tylenol. 2 years later, I'm still having issues: dizziness, lightheaded, fatigue, headaches, fullness & pressure in my head, etc. I do what I know to do b/c it seems going to the doctor is useless. But it has been comforting to know that long term side effects are common, especially when I hear so many health care educators say 10-14 you should be back to normal. False. Everyone's body is different! And so is their healing process.
