hallo there, i am from south africa, my husband is a dentist . diagnosed with klierkoors coxsakki virus 3 years ago via bloodtests. he gets a beriglobin injection every 3 months, if he is due for that, i can see the difference in his behavior. eat more, gravings, depressed, dont sleep well....is this normal...can he really feel that bad, or am i just hard on him, even if i dont show it towards him....does this medical condition really excist or is it just a mind thing??? desperate....
