Is this a general term when drs don't know whats wrongs with you?

I’m wondering if this is a general term used for something the drs don’t know whats causing the symptoms what can be done to avoid or prevent coming in contac with the virus?

hello…
great question…as i thought that myself when i heard about people with fibromyalgia or chronis fatigue…i found out its very real.
a blood test will show if you have epstein barr…it will show an infection along with your symptoms.
.there is no way you can not get this…mainly cuz we all carry it in our systems…it is a dormant little sucker but if the situation is right…mine showed up after 4 months of a drug resistant pnuemonia and my immune system was gone…it pops up.
it can be treated with anti viral meds…u need to take vitamins…i was told flinestone chewables were great for a vitamin…u need to be retested for the virus because if u do all you are suppose to do…it will become dormant again…it will pocassionally show up…as mine did this week…but u just have to follow the rules and do what the dr says…
a blood test is mandatory before they tell u what they think u have…
good luck!
