I Have Been Diagnosed With CFS, Preceded By A Mono

I have been diagnosed with CFS, preceded by a Mono infection that lasted over 6 months and was diagnosed as Chronic Mono. I have a positive epstein barr (?), and also ITP (idiopathic thrombo....platelet disorder). Anyhow, I have recently been experiencing choking on saliva; occasional slight numbness on feet, lower legs, hands/lower arms; more often weakness on legs & arms to the point my foot drags or my knees buckle or I can't continue to use steering wheel; some dizziness/vertigo; extreme vision changes in the last year. My question is are all these related to CFS?
