30-second answer

Some tenderness in the first days is normal as your body adjusts — but lasting or worsening breast pain isn't something to push through. Engorgement and a clogged duct feel like heavy, tender fullness; burning pain that continues after feeding can mean a yeast infection; sharp pain after cold with color change points to Raynaud's. If you have a fever or a hot, red, hard area, contact your doctor today.

Normal tenderness vs. real pain

In the first days of breastfeeding, your breasts can feel full, heavy, and a little tender — that's normal adjustment. What's not normal: pain that keeps you from feeding, pain that worsens, or pain with fever. If it hurts enough to change how you feed, it's worth identifying.

Engorgement and clogged ducts: heavy, tender fullness

Engorgement is general fullness as milk comes in; a clogged duct is a specific hard, tender lump. Both respond to the BAIT approach — ice between feeds, an anti-inflammatory like ibuprofen, rest, and gentle hand expression toward the nipple. Heat and deep massage can actually make a clogged duct worse.

Burning pain after feeding: possible thrush

Burning or shooting pain that continues after feeding, often with a red, shiny, or peeling areola, can point to a yeast infection. This needs a professional diagnosis — treatment usually involves both you and baby.

Sharp pain after cold: Raynaud's

If the nipple turns white, then blue, then red after feeding or cold, with sharp pain on rewarming, it may be Raynaud's — a blood-flow issue, not an infection. Keeping warm often helps.

Common causes: engorgement, a clogged duct, a yeast infection, or Raynaud's. The type and timing of the pain points to which one.
