Thank you all for your help. It really means a lot.
I bought the pump new in July, and I was using it once nightly in the first month or so without any problems. I had sore nipples since the very first day and got plugged ducts every so often, but that didn't really bother me. Other than that, everything was going well.
We went on vacation for two weeks in November, so I started pumping more. I also noticed that my nipples would be more sore than normal after nursing, but I figured it was because of the unfamiliar environment. I also went back to work on Dec 1. The pain started when we got back after Thanksgiving, and it was a shooting pain that occurred only after nursing. It would start at the nipple and move outward, stop for a few seconds, then start again. They would last quite a while but would go away once I started nursing/pumping again. They didn't happen after every feeding. At first, it was only after I breastfed, then about a month ago I started getting the pain after pumping as well. I noticed that I usually got the pain when baby didn't completely empty me out. I would try to pump immediately after, but by then it was too late and the pain was there.
I suspected thrush, so I went to the doctor. My doctors (GP, OB, and an Urgent Care doc) weren't convinced that it was yeast and told me to try aggressively massaging, because they thought it was probably just plugged ducts or something. I convinced my GP to prescribe me Nystatin, but she was reluctant to prescribe anything else. I used that and got baby on it as well. I asked my OB to prescribe Dr. Newman's APNO, but he said I just needed to use Lansinoh lanolin, but that was what I was using and read that wasn't good for thrush. I tried clotrimazole and taking GSE and acidophilus, but nothing really happened and the pain continued. I was about to try gentian violet, but before I did, I wanted to see someone else and get their opinion.
I went to an IBCLC who said I might have Raynaud's because she noticed blanching on my nipple and said vasospasms mimic thrush symptoms. She had me try some Chinese herbs, but those didn't work. So, she said to keep warm and take vitamin B and calcium. That helped a little bit along with using a hot water bottle before and after the feed, and I thought it was pretty much under control for about a week and a half. I was still having pain, but it was more bearable than it had been, but now they're bad again.
This pain has consumed me, and I feel bad for my husband and baby. All they hear about is how much my boobs hurt. I find myself Googling my life away. I'm ready to try anything at this point. I asked my doctor if she would prescribe me nifedipine as an LC at the hospital I gave birth at suggested. I might go ahead with gentian violet too if that doesn't help. I'm just exhausted.
