Hi @shirl3924, how are you and your husband doing today?
Did your husband start antibiotics already? Are they helping? I'm not a medical professional, but I assume they suspect infection somewhere if antibiotics were prescribed. Like @marylou705 said, it may be an infection elsewhere.

I know you are frightfully worried. But as @merpreb said, try to focus your worry into action. Your questions are good questions. When you see your husband's medical team this week as how all these tests are connected. Repeat back to them what you understood them to have said. This will help remember what they said and expose anything that you may have understood incorrectly or that they didn't explain thoroughly enough.

Have you been able to find a way to help your husband feel comfortable?
