Possible clogged milk duct?


I’ve been EBF and I believe I just got my first clogged milk duct. I don’t understand how I got one if LO feeds regularly and eats from both sides. My breast dont overflow what’s so ever... I never leak or anything of that, not even engorgement. I feel hard lumps and area is red. I took a hot shower yesterday and it went away but then came back minutes later. I feed her this morning with the nose to the area as I read on previous posts and it went away but it came back again! Any tips? I also tried my ETB but the back side doesn’t feel the vibrations as much ( Sonicare Philips)
