Wound is Growing, Getting Larger


Wounds may expand during the first week after they occur. This is a natural part of the early phase of the healing process for some wounds. However, after this early stage, enlargement of a wound is a sign of a problem. When this happens, something is causing tissue destruction that is overwhelming the body's attempts at repair.

Wounds can enlarge for a variety of reasons including screw worm infestation, bacterial infections, or sarcoids (which often look similar to granulation tissue). Birds occasionally will pick at wounds on live horses.
Wounds also enlarge under an improperly applied bandage that places excessive pressure on the wound.

If a healing wound is enlarging, a serious disease process may be occurring that requires veterinary assistance to resolve. Assess the wound and take a photo of it and share your findings and concerns with your vet.
