Breast issues....want to try breastfeeding 🤱

When I was a child I had a heart operation (an incision on my left side) as I grew up this has caused my left breast to be pulled to the side.

When I or my husband touches it the nipple often feels numb but this has been the case for many years so nothing new there!

I want to try breastfeeding when our baby is born but not sure whether feeding from one breast only is ok? Would I be able to feed from my other one too?

Do you think my midwife could help with this issue or is it a GP?
