I was diagnosed with west nile virus in 2003. For the last 2 to 3 years i have had an ongoing headache, dizziness, short of breath, memory problems and dry cough. It went away for a couple months...them it returns. I am curious if others have had these symptoms. Doctors cannot find out what the cause is...after a bunch of MRI, cat scan, ultrasound etc. I was also diagnosed with pelvic congestion syndrome... wondering of that could be related?
