I amb a bit of a mess at the minute. DS3 is 3 months old and bf. I have had mild mastitis twice in r breast. Seemed to heal with paracetamol and massage. But r breast became very sore starting last weekend. When he latched became more painful each day, had stabbing pains in breast too. Thought it was thrush,although mouth clear. Made app with gp for next amb.Overnight r breast became AGONY. Rock hard, swollen and VERY sore. Gp said mastitis and possible start of abscess. Gave antib's. But these have given me SEVERE abdo pain. Can't eat or sleep. R breast is getting better. But l breast is now agony when he feeds! If it is thrush-which it must be-how do I treat it? I'm miserable. Sorry so long too. Thanks.
