Blister like area popped under areola stitching? (photo)

Had a donut lift with with silicone implant unders via under breast 8 weeks ago. A blister like spot appeared under my areola stitching. Upon slight pressure applied, the area stuck out as if it were blowing a bubble. The blister then popped, having clear fluid followed by blood. I'm now left with a small hole. What caused this and what should be done?
