Wow, poor little thing! That has definitely put things into perspective. I definitely know that this is worth it, just hoping that this doesn't mess with him later on down the line. But your story has reassured me, thank you. I'll still have a chat with the vet tomorrow just to be sure of everything.
You always have to get through the acute crisis you are faced with first before you can think about the long term. It can be physically as well as emotionally very draining and exhausting, not to mention the hemorrhaging of your purse.
Because of that, I have started to reset the clock at any potentially life threatening condition/op and start to count this as a new lease of life. It helps me to appreciate the extra time I have with a piggy that I would not have had with the ones in the olden days.
It is any vet's job to weigh up the pros and cons of each medication they prescribe for any given problem. Vets are now more generous with supportive meds (painkillers and gut stimulants) than they used to be, which makes a real difference for the piggies in terms of comfort level. Tramadol is the one I would be most worried about for long term use; your vet will take your boy off it as soon as he feels it is safe to.
