Hi blusunflower & I want to Welcome you to SR and particularly this Forum. My son has gotten an infection like you're talking about and they did test his blood while dealing with the infection. They routinely check the liver enzyme levels. Everytime my son has gone to the hospital, the Drs. have found out that he was using drugs or drinking lots of alcohol. It's always turned out best for us that way because they confront him and bluntly tell him what the medical consequences of his actions will be. They never have contacted the authorities because of this. When he got the infections, he told me that he cut his leg on the shower at someone's house, but it turned out that he was using needle drugs.
I do wish that they could fix our loved ones at the hospitals. Hang in there, and take care of YOU. (((((((((((Caring Hugs)))))))))))
