Hi A.,
J. the Lactation Consultant here. :) There are a couple things that may be going on. First - if this is the first time you have been pumping the flanges may be too small. Watch how the nipples come into the flange. Is there plenty of room for the nipple or does the nipple rub on the sides of the tube as it is pulled into the flange? A snug fit is not desireable. If the sides of you nipple are making full contact with the tube of the flange - go get larger flanges. Medela makes 4 diffeent sizes. You are most likely using the 24mm flanges which come standard with all kits. There are also 27, 30 and 36mm. I'd try a 27 or 30...
If this is your problem then rather than using Lanolin (which can cause ssensitivity on its own - many people are allergic and don't' realize it) try Motherlove Nipple Cream. Lanolin doesn't have any healing proerties of any kind. Motherlove nipple cream does. You can also simply use Polysporin antibiotic ointment to help the nipples heal. These two products will actually help heal the nipples - unlike lanolins which only moisturize and if you are sensitive, can make the problem worse. Soothies are fine as long as you don't have thrush.
The other thing you may be dealing with is thrush. Contrary to other advice Lanolin is NOT appropriate to deal with thrush. Also, using soothies if you have thrush just spreads it around more. Not waht you want to do. Getting a prescription for Diflucan should be a last resort not a first. Diflucan is a strong medication and to treat breast thrush you need to be on it for 2-4 weeks. You will also need to have your liver enzymes checked as they can raise in some people taking diflucan - that isn't a good thing.
To figure out if you have thrush a couple things to note: Do you have itching or burning? Does the nipple shine when it is dry> It is red or pink? You may have all these symptoms or just a couple. What about baby? Does he have white patches in his mouth? If you have thrush he will have it too - even if he is not showing symptoms!
Treatment of thrush is as follows: Gentian Violet (GV)- a purple liquid that you paint onto your nipples twice a day. It can be hard to find - check walmart - they can order it for you if they don't have it - costs all of $2-3 bucks. You use a q-tip. Wet one end of the q-tip - using the applicator stick on the end of the cap of the GV purple the wet q-tip. Paint ONE nipple and areola purple and let air dry. Repeat this process with a new q-tip for the other side. Treat twice a day for 4-5 days. Yes, baby will get a purple mouth when he nurses - this is FINE - this way he is treated too. :)
While using the GV you will also want to use an all purpose nipple ointment (APNO) Use equal parts of: Polysporin ointment(NOT neosporin!), hydrocortine ointment and miconozole cream (yes the vaginal yeast cream) (NOT clotrimozole!). Massage these 3 into the nipples and areoals after each pumping/nursing sparingly - just leave a shine. There is no need to wipe off before pumping or feeding unless you really want to. Use this for at least a week after all symptoms have gone away. Keep air exposure on the nipples at all times. Get breast shelss to wear in your bra to keep everything from touching the nipples. It feels better that way and helps to speed the healing.
You can find more information on thrush treatment by typing Jack Newman into your search engine. He has lots of good info out there. Or, if you have other questions or need help determining exactly what the problem is please feel free to call me any time at ###-###-####.
I wish you luck in this! This is a yucky place to be...I've been there myself and I have worked with too many moms in your circumstances over the last 13 yrs...
Take care!
Warmly,
