Is throbbing and aches/pain normal almost 4 weeks after breast augmentation? (Photo)

I got my breasts done 3 weeks 1/2 wks ago (325cc silicone submusc.) and the left breast was the more swollen and painful breast (it's the slightly larger one). I've always felt weird shooting pains on and off but knew this was normal. My breasts look great so far, no bruising but the left breast just yesterday started to get a throbbing/shooting pain in it like a trapped air feeling. The pain increases when I laugh or take a heavy breath. It almost feels like the ache is in my left arm as well.
