Ouch! Am I blocked???

Sarah

So my sweet husband decided to let me sleep extra last night and gave the baby a bottle of pumped milk in the middle of the night. I didn’t even realize it - the baby was crying she then she wasn’t and I fell back asleep. Well then I woke up this morning at 5 feeling super super full so I pumped and got my usual amount but my left breast is still in a lot of pain in one spot. I tried putting a warm wash cloth on it and massaging it, but it still hurts. Milk comes out so I’m not sure if I’m really blocked or not but that spot hurts sooo bad especially when touched. What is going on? And how can I make it stop??
