My episiotomy and 2 internal tears got horribly infected (took 2 weeks of 2 sorts of antibiotics to clear) and the bum-cheek end of my extended episiotomy came undone as well. Sending so much sympathy your way: it is utterly miserable.
HOWEVER, I’m a year on now and the scar has healed beautifully. The bit where the stitches popped did a ‘granular heal’ so is a bit less near than the rest, but not really noticeable. Do you have any stitches left in or has the whole lot opened up?
My main advice would be...
Lots of air - no bottoms on in the house and get puppy pads to sit/lie on for the bleeding (remember not to answer door to postman with no pants on
)
Keep on top of painkillers especially if it’s just paracetamol because of breastfeeding - it works so much better when you do evenly spaced doses rather than waiting til you’re desperate.
If the pain is still bad when you’ve finished antibiotics go and get checked again; once mine had actually done their job I was amazed how much of my pain was infection rather than the injuries themselves.
Know that 5 days is no time in terms of healing - it’s a slow process but you will feel so much better again eventually.
Keep in mind that just getting through this bit is a win. You’re doing brilliantly.
