What you describe sounds very familiar to me. I want to give you the information for the doctors I spoke with first, because I think they were excellent. My story follows after.
Dr. Cliff O'Callahan, in Middletown, CT ###-###-####) did the procedure for my son. He was the closest thing we found to Millerton, NY. I would highly recommend him. He was great, explained everything, had excellent bedside manner with me, my husband, and my boy. I also spoke by phone to Dr. Elizabeth (Betty) Coryllos, a pediatric surgeon who also specializes in lactation and frenulum problems. She's supposed to be an expert on the subject. She's on Long Island (Mineola) and was willing to speak with me for free over the phone. ###-###-#### & ###-###-####).
We did it when he was 4 months old, fully awake, just some local anesthetic. It was simple and over quickly. There was a little blood and a lot of angst - mostly about his head being held tightly - and then it was over in less than 5 minutes. The Dr recommended I nurse right away to soothe him.
My son had a more hidden tongue tie . . . that's why it took until 4 months for someone to see it and suggest the idea of getting it snipped. To be honest, by the time we did it, I was nursing so rarely that I can only say it *seems* to have helped. The later in life, the longer it will take for him to relearn a different way to use his tongue, so the results are not as dramatic.
My opinion? If they can see he has a tongue tie, I see no reason NOT to get the snipping. I had the exact same nursing situation as you (minus the C-section). A ton of pain, could never get it to work right, was on the same crazy pumping and feeding regimen you describe until I just couldn't do it anymore . . . Between the pain and the formula supplementing I had to do, my supply never really got going properly. Of course, he preferred the bottle. I went through every other idea you can imagine, and its remedy, before we found the tongue tie. By the end (six months) I was pumping 3-4 times a day and feeding him maybe 4-6 oz total to supplement his 18 oz of formula.
You can never say what might have been, but I wish I had the information you have now at 3 weeks . . . I think I would have done it ASAP. Why "hang in there" when the procedure is so simple and relatively risk free and could be so beneficial.
One last thought. Dr. Coryllos explained to me that this used to be a completely standard procudere that every pediatrician learned. It would happen as a regular procedure to most kids right after they were born. It fell out of fashion and stopped being taught in med school. I don't know why, maybe because they felt "Let's not do unnecessary procdures?" (Which I certainly respect). But she believes that it is one part of the reason why so many moms have pain breastfeeding. Feel free to email directly if you have anymore questions.
