It's so frustrating, isn't it?

Did you try the ultrasound? I have found that really good for getting rid of lumps. The physio does the ultrasound, then I feed DS, then she does another round of ultrasound.

Some other things I have found helpful are:
* lecithin capsules (I am taking 6 a day at the moment)
* showering in the morning, rather than at night - and massaging out any lumps that have developed overnight
* ice packs on the lump after feeding
* making sure the boob is fully drained at each feed - even if I have to express after DS is done
