Thrush still :(

It is Jan 22, 11 and I still continue to have thrush. I went to the doctor last Wen. she was a new doctor and she does not seem to realize how long I have had this and all of the ideas I have implemented to try and get rid of this stuff. She gave me another round of Nystatin Ointment. I called in to try and get a prescription of antibiotics to take but she won't give it to me even though the peds doctor and the lc say it is safe for the baby. If this round of ointment doesn't work I have to go back to the doctor. :( It is very difficult to pump while fighting thrush. My nips are real tender and hurt. I have had 3 milk blisters now and it is taking me an 1hr to 1 and a 1/2 hours to pump 2 5 oz bottles. I do wish this stuff was gone. I thought pumping for 30 minutes was tiring.
