I went out Friday after work with Jim and we checked both of our mares over carefully. No nasal discharge at all, and I very carefully and thoroughly felt each lymph-node. They both were very happily munching on hay and wasn't too pleased with me interrupting dinner, but such is life.
The first horse to get Strangles still has pretty large lymph-nodes and is still coughing. Vet said to still keep her away from the others. The abscesses have stopped draining and are healing up.
