Severe muscle pain at night 2 weeks post op breast augmentation. Is it normal?

I used to be barely a 32A, had textured anatomical shaped 350cc placed sub muscular on 2/17. Being very involved in boxing, my PS said I had thicker than normal muscular tissue. It has been a very painful recovery, I finally stopped needing Percocet at the beginning of this week, Motrin covering the pain. I am now waking up at night with extreme pain in my left muscle, needing Percocet and Valium to fall back asleep. Is it ok to ask for a refill of my pain medications this late after surgery?
