So far I've told my friend to do the following.
Apply arnica cream and take arnica tablets (must be 200C, anything less isn't strong enough).
Have a salt bath.
Put 10 drops each of tea tree oil, distilled witch hazel and lavender oil in the bath and also on pads.
Put 100% Aloe Vera gel straight from the plant in the fridge and then on pads.
Put pads in the freezer.
Boots and Mothercare do small gel packs you can put in your knickers under your pad. They also do ones you can put in your bra for when your milk first comes in.
Use Aloe Vera wipes
If you have anything to add I would be really grateful.
Also has anyone tried putting aloe vera gel straight into the bath?
