Eek, that sounds like pretty negligent advice, how would she even know where to stick it?!
God, the thought makes me sick and can you imagine if she got it wrong and got a nerve?
Anyway, I have had this a couple of weeks ago, after reading advice on here and kellysmom I worked ALL NIGHT trying to relieve it.
I kept baby feeding from it, as doulalc said different positioning so baby can drain it for you.
I massaged it down towards the nipple whilst baby fed.
I got in a hot bath and massaged it, really deep tissue massage.
Hot and then cold flannels.
Expressing.
Then when I was tired I filled up a hot water bottle with boiling water and put towels on the breast then the hot water bottle, then the duvet over the top and slept with it on.
In the morning it was gone, thank goodness. The relief was amazing and I was defo in the first stages of mastitis from it, fluey, achey etc and working on it got rid of it.
Now, your friend needs to ask herself why she's getting them.
In my case it was because I hold the breast in a C-hold too tightly for the baby to come to. This lead to a blocked duct on that side of the breast. Now I feed with a loose hold (and non at all when possible) and my bra undone.
Your friend needs to find the reason for the blockages as it's more than likely something she's doing subconsciously. My friend got bad mastitis (which starts with a blocked duct - as you prob know!) from wearing a proper bra with underwiring and everything! for a posh do with a posh frock.
