Common Causes (Rider-Level)

Soft-Tissue Strain

  • Tendon/ligament irritation after work, misstep, or footing change
  • Heat/tenderness along the back of the cannon or around the fetlock

Cellulitis / Lymphangitis

  • Rapid, painful swelling; skin tight, warm; horse may be systemically “off”
  • Urgent veterinary care is needed—call your vet

Joint Effusion / Trauma

  • Fetlock, hock, or knee looks fuller; may follow a knock or twist
  • Check for wounds; cool and consult your veterinarian

Wound / Bite / Foreign Body

  • Puncture or cut with swelling; insect/snake bite possible
  • Do not occlude a draining wound without veterinary guidance

Bandage / Boot Issue

  • Uneven tension or slipping can create localized swelling
  • Remove, cool, and rewrap correctly only if advised

“Stocking Up” (Usually Both Legs)

  • Cool, even puffiness after stall rest/travel
  • Improves with 15–30 minutes of movement

Heat, pain, lameness, wounds, fever, strong pulses, or rapid change = call your veterinarian.

First 10 Minutes — What to Do

Cool & Check

  1. Stand down from work; move to a flat, quiet area.
  2. Hose or sponge with cool water and scrape between passes (5–10 minutes).
  3. Compare legs at the same landmarks; check heat, tenderness, and the digital pulse at fetlock/pastern.
  4. Photo/measure the area to track change.

Wounds, heat + pain, lameness, or fever—skip DIY and call your veterinarian.

Routine (If No Wounds)

  1. On intact skin, apply a THIN layer of Draw It Out® 16oz Gel.
  2. Allow hair to go dry-to-touch (absorb) before pads/wraps.
  3. Optional standing wraps with even tension; recheck at 15–30 minutes for heat/tension/slip.

“Wrap-ready” = thin gel → absorb → gear on. Use on intact skin only.

One Leg vs. Both (Quick Compare)

One Leg (Unilateral)

  • More likely injury, infection, joint issue, or bandage problem
  • Heat/tenderness and stronger digital pulse are common
  • Often needs veterinary evaluation

Both Legs (Usually Hind)

  • Cool, even “stocking up” improves with movement
  • No pain, no lameness, normal digital pulses
  • Monitor after a 15–30 minute walk/turnout

Use the Horse Leg Anatomy map to compare the same landmarks every time.

FAQ

Can I exercise a horse with one swollen leg?

No—stand down until your veterinarian evaluates it. Gentle hand-walking may be advised after cooling, but hard work can worsen injury.

Should I wrap right away?

Cool first. Wraps only on intact skin, after full absorption if gel is used, with even tension and ~50% overlap. Recheck at 15–30 minutes. When in doubt, ask your vet before wrapping.

What if swelling returns after it goes down?

Recurring unilateral swelling deserves a veterinary workup (soft tissue, joint, infection). Track photos/measurements and note workload, footing, and travel.

Where do I learn a safe routine?

Start with the Recovery Loop (daily plan), the Wrap Method Guide (safe wraps), and Horse Leg Anatomy (landmarks).
