Blocked ducts!

Had a case of bad blocked ducts on the thursday before we left for the US! Went down to TMC and had it cleared. There was a white bleb and after the LC got the bleb out, and Kieran suckled, it was instant relief. The pain and swelling went down immediately! I thought that everything would be ok, but this problem has been recurring! I saw the bleb appearing again the day before. I managed to clear it and now it's back again. I can feel the same part of the boob hardening again. I think it's got to do with the time difference and Kieran drinking less milk at times where he would actually drink more. It really hurts when he is sucking on the sore breast! Got to get this problem fixed. Looks like I've got to clear it and massage it everyday just so that it doesn't recur! This is so weird, cos such things usually occur in the beginning stages of BF-ing and not when Kieran is already 6 months old!
