If your spouse suffered an injury from an accident or a fall, this should be seen as the most alarming sign for the family. If your spouse fell, were you with her or him? How bad was the injury?
If your loved one was unable to get the needed help in a timely fashion and the prospect of another fall would make the situation even worse, then this is probably the right time to consider getting some help.
If your spouse fainted and you weren’t there, then you might want to consider getting an extra hand. If you think about it, it could be completely dire if she fainted again with no one around.
