A swollen limb
After being tagged in a clipping post by professional equine clipper Aaron Campbell Equine Clipping Services, where a client was advised to seek veterinary advice, we felt this was an important topic to highlight.
A horse can have a swollen limb because of several reasons, in this case it was a cellulitis/lymphangitis.
Cellultis is an infection of the tissues, while we call it a lymphangitis when the lymphatic system is affected. We often cannot really distinguish the two but they present and are treated the same.
Symptoms include:
• Sudden, severe swelling of one limb that is hot, painful, firm, and often has pitting edema
• Marked pain when the leg is handled (snatching away, lifting high, nearly losing balance)
• Lameness, stiffness, and reluctance to move; painful, even at the walk
• Horse places the foot usually still flat (unlike a foot abscess, where they can tiptoe)
• Skin may look shiny, stretched, or thickened/“woody”; oozing or sores can appear
• Systemic signs are common: fever, increased heart rate, depression, decreased appetite
Veterinary assessment is recommended.
Treatment is tailored to the individual horse and usually involves anti-inflammatory and antibiotic medication.
Steroids may be used in selected cases; however, they are avoided in overweight native-type ponies due to the increased risk of laminitis and in pregnant mares due to risks around the pregnancy.
Depending on the severity of the condition and the patient, treatment may be initiated with intravenous injections or with oral medication.
It is important to provide these horses with regular, gentle forced exercise—even when they are painful—as this helps reduce swelling. Cold hosing can also be beneficial to decrease heat and inflammation, especially at the start when walking is difficult, followed by thorough gently drying with a clean towel.
On the European mainland, this condition is also called “elephantiasis,” which is easy to understand when you see the swelling. The pictures shown are of a former severe case. That case improved significantly after several days of very intensive care by the owners, including a lot of forced hand-walking.
