My right breast is sore with back muscle spasm after 4 weeks post op. Is this normal?

I am 4 weeks post op. 500cc silicone implants under muscle. My right breast is sore and there has been alot of air bubbles when I move. The incision looks fine not red/ no rash. I have had sharp pains as well. The right implant looks like its dropping more towards the right side and not straight down like my left is dropping. I did wake up half on my tummy this morning... Also having back muscle spasm right side. Not sure if any of this is normal after I been fine 2 weeks ago?
