Did the vet check him for an anal fissure? If he had that it does take awhile to heal, and it hurts and burns like the dickens when they try to Poo. He could have had that because he was so constipated at first.
Sudden and severe pain in or around the anus is the main symptom of an anal fissure. The pain often occurs during or shortly after a bowel movement, but may also occur at other times. This pain can be severe - and is often described as like passing razor blades. As a result, a fissure sufferer is likely to dread opening their bowels. |
