My grandma cut her leg now it's leaking fluid?

Go to Urgent Care: Get her to an Urgent Care or ER if the fluid is more than a tiny ooze whether or not it's blood. As an elderly woman of unknown medical condition, this could be a serious and correctable issue. So, go. If it's not necessary - ask for ways you can better evaluate this decision in the future. Thanks for being a good grandchild! Best!

Possible infection: Fluid weeping from a wound may be related to infection. Please have that evaluated be a physician.

Depends : This could be a normal response to a cut in an otherwise healthy person, as local tissue inflammation results in some weeping of the affected area. In older persons, especially those with lower leg fluid retention or poor circulation, additional measures should be taken to ensure proper healing and prevent infection. Suggest in-person evaluation with a doctor to be safe.

Pressure/dr: Please get a clean towel and press on the cut until the blood clots right now, then the leaking will stop, unless this happened a few days ago, in which case, it could be normal or could be infection. If an old injury, please take her to an urgent care center or her doctor when possible, clean the wound with water, and treat it with antibiotic ointment and place a sterile dressing over it for now.
