What Causes Shivering And Tiredness With Eyes Glossed?

hi doctors. On sunday night I when i sent to bed i was shivvering under the blankes but i had NO feaver. The following morning I was feeling very tired and my eyes were glossed over so I sent to my internist who said there was nothing wrong with me. on tuesday I had pustulates that itched covering my scalp, around 60 on my chest and back, ten on my face and some on legs. at first I thought bug bites or bed buges so I saw a internist that same day who told me that they were not bug bites but that i might have had adult chickenpox. i had chickenpox as a kid. today i saw a infectious disease specialist who thinks it is some random type of viral infection but not chickenpox (but couldnt say 100 percent not) and definately not shingles. i am 46, in great health and have hsv1 but ive never had a sore only detectable in my blood. the doc does not think this is a herpes reaction either. what do you think? he put me on valtrex in any event
