Is Hepatitis, Related With Sweating, Breathing Issues And Loss Of Appetite?

my husband is having lots of trouble breathing...coughs constantly, he has been sweating like crazy and he has these scabs on his head, also he has no appetite and has been vomiting for about a week...the chest x-ray he did came back normal, but he has been taking this stuff called Sam-E and the doctor thinks he may have hepatitis?
