I’m not sure how deep but the bottom of the wound is about 2 to 3 cm long It not closed since last op wich was in December the top bit has healed but there’s 1 area at the top of buttocks wich opens and closes It use to leak fluid also but now it’s not bad I just opened back up couple days age not that big but still a problem the bottom bit is where I am worried about no progress what so ever I was meant to have a phone call appointment with the surgon who did the 3 operation on me but did not ring I rang the hospital and they said he wrote on his notes he spoke to me haha they re booked me in for 2 weeks
