Sharp pain in leg after lipo (4 weeks post)

I had leg lipo 4 weeks ago, most of the bruising is gone, I'm still sore though. I'm mostly concerned about this stabbing, piecing, stinging, sharp pain in the back of my right leg. It hurts without touching it, but when I press on it, it feels like a piercing, hot, pain shoots through my leg. Is this normal at the 4 week mark? If this is normal nerve repair, when should this resolve? Thanks
