What To Do
This is a serious situation. Without identifying the underlying problem - a diagnosis - you are gambling with your horse's life. Repeated bouts of colic suggest the presence of a life-threatening disease. Now is the time to talk to your vet about figuring out what is causing your horse pain, and explore your options to resolve it. This will require physical exam and a variety of other diagnostics.Assess the horse's general health using the Whole Horse Exam (WHE), and contact your vet with your findings and concerns. Be prepared to discuss the history as this may offer clues to the nature of the problem.
What Not To Do
Do not just assume this is a chronic colicer, and take this situation lightly. A diagnosis should be made.
