I feel exactly the same and had my baby on Wednesday! X
If your bottle feeding try not to touch them at all (easier said than done I know!😆) Any stimulation will keep the milk producing. Take ibuprofen/paracetamol regularly to help ease pain. It does ease up in a few days I promise. X
I had this as well and I can sympathize, the pain was horrendous but trust me it does get better within a couple of days. I found a hot shower or bath helpful, I would massage my boobs gently and then hand express a little to make it slightly more comfortable. Just keep feeding to demand and it will sort itself out soon xx
Hand expressing a small amount is supposed to be good for relieving them without signalling to your body to make more. Eg. A baby would be feeding constantly to encouraged supply therefore hand expressing a tiny mount for relief should not stimulate supply!
