Hermione gave her Healer a look that clearly said See when Ron agreed with her. "You won't even have to do anything," she pointed out. "And I promise I'll get right back into bed afterwards. Please?" she added, just for good measure. Not that she was really asking, she would convince Ron to take her into the adjoining bathroom as soon as the Healer was preoccupied if she had to.
But he relented after a moment, though made sure that she knew he wasn't happy about it. Hermione could care less about his feelings on the subject, however. She was getting a shower, that's all that mattered.
"Thank you," she said to Ron, as soon as they had been left alone. "I feel awful, and that's all I want. I've been trying for hours."
