Yup, it's a bleb, aka white spot or milk blister.
I had a recurring one, quite painful. It never really went away towards the end. I popped it a few times and got milk out but after a while I would pop it and it would only bleed. The only help I got was when you pop it you have to express milk or whatever it was that's blocking it in there. I had it on and off from about 6 months to 18 months when I weaned, partially because I was sick to death of being in pain from it.
