Yup sounds about right. Try to pump, but what really helped me is being in the hot shower and massaging your boob wherever the affected area is.
How old is baby? Maybe you can even try and take one regular Tylenol. (Even 2 depending on the dosage)
@gutierrezchristy, My whole body is hot! No more lumps had a big one this morning... it is a very tender spot though and I have a fever
Then it's just a matter of time. It's the most painful thing to go through.
Also, pump after feedings and change baby to different positions
