I have had mastitis 3 times this year. It is awful Anna - so sorry for you. I found paracetamol really helped with the flu type symptoms. also, I took a hot shower every morning and every night, putting the shower head on the affected boob.Afterwards, do a feed, or express until all the milk has gone. Then, massaging the area through the day, and making sure the boob is empty after a feed. The first two times I had antibiotics, took a week to fully go though. Third time I avoided the antibiotics, caught it early i think and used the method above. Good luck. Oh, and the most important thing, which as a mum I know is pretty much impossible, is to rest as much as you can. Take any help you can get, because rest and naps will honestly make a huge difference. xxx
