Hello there, I am from India I have a small pox infection in year 2009 and after that next year in 2010 I devloped a flu like illness with low grade fever after rigorous regimen of exercise for two months. And after that I devloped something I came to know as CFS/FMS/ME/POTS/PVFS. I AM NOT ANYTHING OR ANY KIND OF TREATMENT FOR FIVE YEARS TILL NOW. I started to look into antiviral in recent months and I am taking Valcyte 2gram increasing it gradually in two weeks. And I am on 60 to 70 percent of pre illness with pacing and maybe on 5 EIPS. And I have sore throat or flu like illness in the morning while I am taking it?
