I recently discovered a sore spot in my left armpit that feels like a bruise when i push on it. I've had that for roughly 3 days. I woke up this morning and found a lump the size of a pea in my right armpit. there is always a slight sensation at the location but it only hurts if i touch it or stretch my arm over my heads. I am 20 years old and male. Can anyone tell me if this is serious or not?
