This is what my vet said:
Warm wet compresses. You've got to get the dried milk/colostrum plug out.
Roll the teat between your fingers. Can you feel the plug? You're going to have to moosh it out.
Steam some shredded cabbage and apply to the udder as a compress.
Feed her Vitamin C chewable...
I would try warm water in a bowl, dipping one teat at a time let it soak a couple min. while gently messaging them. Then Dry them and then try milking her and if it doesnt work repeat.
