I am glad you are seeing a LLL Leader, that should be very helpful, but (just in case you need more help) I will just remind you and anyone else that LLL Leaders are not lacatation consultants. Well, some are, just as some are doctors, nurses, lawyers, chefs, and dog walkers, iykwim. But as LLL volunteers, we are trained to help moms dealing with issues that come up "in the normal course of breastfeeding." What you are experiencing is outside that norm so seeing a professional, clinically trained and educated IBCLC may be needed.It's someone from the hospital. One of my friends has hooked me up with someone who is going to come over to help me though, so maybe that'll be better! I think it's a LLL volunteer person :-)
Some WIC offices have a lactation help dept. Some have only peer counselors, but some also have free appointments with IBCLCs. Have you asked them? You can also ask the LLL Leader for names of private practice IBCLC's.
As far as flange size-Hmmm. Is your nipple rubbing when drawn into the tunnel, or moving freely and easily? If your nipple is rubbing, you likely need a larger size. Also I think there are companies that make odd sizes or special "comfort" flanges. Pumpin pals is the only one that comes to mind right this second.
An IBCLC is a board certified lactation consultant. They are professionals who have been trained to work with mom & babies who are having breastfeeding issues. Some Lactation consultants are not board certified and are still excellent, but with an IBCLC you know they have had a certain level of education and clinical training and have to regularly be re-certified via testing and continuing education. Personally I think if you find an IBCLC who is also or who used to be a LLL Leader then you are in really good shape.
I am worried lanolin would make the pumping more sticky? If not, then fine, but you could also try olive oil. However, if the flange is the correct size you should not need any 'lube."
