What does Mark say happened to the bleeding woman after years under many doctors?

Answer: She only grew worse

She had suffered much under many physicians and spent all she had, but instead of improving she only grew worse.

“And a woman was there who had suffered from bleeding for twelve years. She had borne much agony under the care of many physicians and had spent all she had, but to no avail. Instead, her condition had only grown worse.”— Mark 5:25-26 (BSB)
