My husband has had a painful white streak on the side of his tongue for months. Finally, today, he had a biopsy taken.
He is extremely worried, so much so that he is making himself sick. He is a very anxious person on a normal day, so you can imagine how he is doing now.

How can I help him? I really don't know what to do.

I am trying to find more information on those symptoms, but of course I can't find anything conclusive online to help me.
