I took care of a school horse who struggled off/on with lymphangitis. He was almost always sound except on the most swollen days, but his hind legs were thick from stifle to hoof. He was on steriods, anti-flam, and antibiotics almost round the clock because his lymphangitis was very hard to manage.
Couple things that I noticed:
- His legs would always balloon after wrapping. Terribly. If he had any sort of wrap on him, the next day his legs would be ginormous and painful. Stable and bandage wraps especially. No matter how clean or perfect the wraps were, any sort of pressure seemed to trigger a flare-up.
- Stall time: if he was kept in a stall for more than 12 hours, he wouldn’t just stock up, he would flare up and be very lame.
- Water - the more OCD the owner was about drying/keeping his legs clean after contact with dirt/water/anything, the worse the flare-ups were. There was definitely a correlation between activity on the legs (rubbing, brushing, drying, toweling) and flares.
- NEVER pick, scratch, curry or rub any scurf, keratosis, crud or scabs on the legs. If there is a cut, gently wipe clean with baby wipe and spray Alushield or WoundKOTE.
Cold hosing did not help him and IMHO it made the flares worse and more painful. My opinion of wrapping is that you better make damn sure the leg and wraps are sanitary and 100% clean otherwise you are just trapping bacteria, dirt and grime in between the wraps and the skin which is bound to have a very reactive reaction in a horse with lymphangitis.
The best thing for him was an absolute arsenal of steroids and ABX and 24/7 turnout. The owner really pushed against it, but after the 200th episode right before PC championships, the vet finally got her to concede and switch him to a 24/7 turnout reigme. He was much better with the forced movement, had fewer episodes and I think the benign neglect was good for him. The owner really was the type to pick and package and wrap and helicopter and IMHO I think it made it worse for him.
He had a whole host of problems and was definitely immunocompromised. He had his own medicine cabinet, that is how much ABX, steroids and joint supplements/anti-flam supplements he was on.
Unfortunately, for him, his other issues compounded the lymphangitis and he was PTS.
