Apples post surgical hernia

hello, our horse Apple had colic surgery in February at Newmarket Equine Hospital.  the surgery went reasonably well and Apple came home 2 weeks later.  He had an infection in the wound but this cleared up and the incision healed very well over the next 10 weeks.  However Apple then developed a hernia along the wound.  We then rested him to see if it would heal itself but no luck. So our vet recommended we go back to NEH for further surgery.  However our surgeon suggested we try the hernia belt from cmequineproducts in USA.  $600 later Apples pacel arrived and on 29th August we started using the belt.
