Luke 8:42-43

The crowd that Luke described graphically as pressing against Jesus and almost crushing Him created the scene in which the woman approached Jesus. The exact reason for her continual bleeding is unknown and unimportant. This condition resulted in her discomfort, inconvenience, ritual uncleanness, and embarrassment. Some commentators believe that Luke’s omission of the fact that she had spent all her money on doctors who could not cure here was his attempt to guard the reputation of his profession. However it may have been a simple omission of a detail he felt was unimportant in view of his purpose. The point is that no one could heal the woman for 12 years, but Jesus did in an instant.
