  • If the area seems painful to the touch.

  • If the problem is subtle or slowly changing.
  • If the results of the Whole Horse Exam (WHE) suggest the horse is otherwise normal.
  • If the swelling is mild or moderate, and not increasing rapidly.

Swelling of the withers usually is caused by trauma, usually from ill-fitting tack. Saddles that have a tree that is too wide, too narrow or broken may traumatize the withers. Direct trauma from the horse rearing and falling over backwards may fracture or otherwise injure the withers, which also can result in swelling.

Large and enlarging swellings of the withers may come to a head (infection may come to the surface) and finally drain. Infections of the withers do occur and can be difficult to treat. These infections often involve the bone of the spinous processes of the vertebrae that make up the crest of the withers.

WHAT TO DO

Assess your horse’s general health using the Whole Horse Exam (WHE), paying particular attention to presence or absence of fever. Consider the history leading up to the swelling. Was the horse recently ridden? Was the saddle that was used the same as always?

Share your findings and concerns with your vet.

WHAT YOUR VET DOES

Your vet will assess the area visually and by palpation. They will assess the horse’s overall health, paying particular attention to the presence or absence of fever. They may want to evaluate your saddle fit.

If there is no evidence of trauma and there is drainage, they may consider the possibility of a bacterial infection (fistulous withers). Radiographs and ultrasound provide additional diagnostic information.

Your vet may advise you to apply cold water to the area or suggest the use of anti-inflammatory medications for pain and swelling.
