It’s impossible to say from the picture and very few providers can actually diagnose oral ties (only those that can clip them). Feeding at the breast for 1+ hour is a long time! I would get looked at for that alone but definitely bring up the other symptoms because I think they are important in this case as well. If you can, I would recommend seeing a speech language pathologist first because they can assess the muscles and movements of the mouth and recommend whether they need to be seen for a tie. Sometimes ties can be stretched out over time but other times clipping them may be necessary. You will need to go over the options with a knowledgeable provider.
I had a similar thing. I will ask my guy who we went to. They were very air on side of dont unless necessary. My babys stretched and grew. They said his tongue wouldn’t stick out. Now he does all the time. Breastfeeding was brutal at first and hed get very upset and i had to use bottle sometime. Eventually left dried a bit prob due to the pain. But i continued. Id say by month 3 or 4 it was markedly better to where i was like its just a little annoying sometimes and now 6 months its a breeze he does both and im glad i didnt hurt my baby for something that naturally would have stretched and turned out normal. Use nipple creams for sure and maybe pump a bit rather than breast if in pain pain. Good luck!
