Hi D.,
Have they also treated the baby for thrush? From what I know you pass it back and forth and both need to be on meds for it to completely go away.
I dont know of anyone on LI but Christina Smillie in Stratford, CT, (just past Bridgeport) is fabulous. Her # is ###-###-####. Maybe she can refer you to someone on LI or talk it over the phone. If you do make the drive the trip is totally worth it. She has been a lifesaver to me.
The blister sounds like a plugged duct to me. It could be preventing the flow of milk, hence the lower supply.
Call Tina, she is wonderful!
Good luck!
