Echo seems to go from one medical situation to another. Today we took him into the vet again but this time for a sebaceous cyst that became infected. He was scheduled to have it surgically removed next Wednesday but yesterday it became swollen and red and developed a lump. I called the vet and he said to bring him in first thing this morning. His cyst broke over night and the vet cleaned it up, helped drain it and put him on antibiotics. After the antibiotics take effect over the next 10 days we will evaluate whether he will need surgery or not.
