Any ideas on when to throw the towel in with mastitis and go to the GP for antibiotics? Woke up yesterday morning with a sore breast and feeling rubbish - got worse during the day and ended up with a 40 degree fever last night. I feel fine again today (maybe it was a virus and unrelated to my boob problem?) but my breast looks worse - one side is now an angry purple colour (yesterday I just had a small red patch) but it only hurts when prodded. Also, yesterday let-down on that side really hurt and today it's fine. I'm doing all the recommended stuff - hot compresses, feeding mainly from the affected side etc.
