Yes, I had 400 and between 1 and 2.5 wks I had a lot of pain in my left, the nurse and my surgeon thought it might be a trapped nerve. I felt really crappy and it was agony to try and walk anywhere for more than 5 mins, my bra felt tight and I was getting really tearful, then just as I thought it would never go it just stopped. I still feel bruised but no pain any more x
