Nodular Necro-Biosis: has anyone else had this?

Sorry for all the new posts, just curious for some ideas!
My horse was diagnosed with nodular necrobiosis on his back (caused by an ill fitting saddle). They are little hard lumps under the hair, and in my boy's case- are very painful. He is on a course of Preddy Granules to make them go away (seems to be working so far), but I was just wondering if anyone else has had any experiences with them? IE how bad was it? What treatment did you use? Did they return?

This is an allergic reaction---odd though it sounds--thus the use of corticosteroids to treat it. For this reason, they often return because the corticosteroids don't "fix" the allergies long-term.

The allergic reaction can be due to insects, materials (such as whatever your saddle pad is made out of), foods, plants, etc. Since most people and animals that are allergic to 1 thing are allergic to several things, it can also be a combination. This was discussed at the 2006 AAEP meeting and one of the comments made by the presenting veterinarians was that doing food trials and removing any feedstuffs that the horse is allergic to from the diet can stop the nodules from developing. Basically you need to figure out what is triggering the allergic reaction and get rid of it or minimize it.

You might want to consider having allergy testing done on your horse to help you pick out the triggers so that you can remove them.
