My mare has just returned from 5 weeks at a stud farm with a partially paralysed face - of course nobody there knows anything about it. Her tongue is askew, she has limited use of her lips for eating and the area under her jaw is inflamed. My vet has looked at it and said it is nerve damage caused by wearing a too tight headcollar 24/7, but I am not convinced. She is well in herself apart from this, appears to be in no pain and is eating and drinking well. Does anyone else have experience of this condition and how it should be treated ? I am told the nerve damage should get better over time. I am using anti-inflammatory gels, but reluctant to give her anything internally as she is in foal.
