Is This Discoloration a Hematoma or Seroma? (Photo)

hi im 27,non-smoker.6/7/12 got a breast lift w/700cc silicone unders. For a week ive had firm dark purple discoloration under one breast, my PS is out of state and wont answer my calls.. ive been to the ER 3 times: 1st visit- DR said "i refuse to even take your bra off and look" 2nd - DR said he wasnt alarmed. 3rd -said it was most likely bruising but wasnt sure. never even seen stitches like mine. i finally found a PS in my city but he cant see me for a week. im very depressed. thank you
