Shooting Pains Normal?

I had bilateral mastectomy & reconstruction 11 days ago. The discomfort has gotten suddenly worse this evening...shooting pains across one breast and general pain in all incisions. Tylenol isn't quite getting rid of the discomfort.  I did have more activity today than I've had in all the 5 days I've been out of the hospital...had a check up with the plastic surgeon. Could that be why I'm so achy? I overdid it? Could the shooting pains and incisional pain just be healing pains? I have a PICC line and am still on IV Vancomycin so I know I don't have an infection. The plastic surgeon said the side with all the shooting pains is healing beautifully. It wasn't painful when I saw him so I didn't ask about it then. The other side isn't doing so well and I'm having additional surgery Friday to replace the implant with a tissue expander and to remove tissue that has died. There's not enough good tissue left to cover the implant. When the area finally heals, the implant will go back in. But that side isn't where the shooting pain is. Incisions on bad side aren't as uncomfortable as the "good" side either. Could it be because good side is healing fast now and other side is not? Is this how you heal from mastectomy & immediate reconstruction?
