I have also been suffering from thrush. Ouch!! I feel your pain. Wearing a nipple shield has helped me get through some of the pain. Your latch might be fine...maybe the thrush comes and goes. I find that I have days that are better than others. Also, you might want to try some tylenol 10-15 minutes before you feed for the thrush pain. Someone suggested a UVA/UVB reptile light. I purchased one over the weekend and used it once along with the gentian violet, grapefruitseed extract, APNO and I seem to be feeling like I might be turning the corner. I used the lamp for 1 minute on each side....it felt like it was a little too long because I felt like I had a sun burn on my nipples all day saturday, but today I feel a lot better. Thrush is an evil beast!
