This is a minimally invasive medical procedure and its risks are real. Your director names them in the room: bruising, swelling and soreness over the treated hip in the opening days; patches of reduced sensation across the outer thigh, common in this region because the skin nerves there run a long superficial course; and, less frequently, a fluid collection, firm nodules under the skin, looser skin, infection at the micro-entry point, or a visible difference between the two sides.
Contour irregularity deserves its own paragraph here. The outer hip is convex and it is lit from the side by almost every light source in an ordinary room, so a dip or a ridge that would pass unnoticed on a flat abdomen catches a shadow on a hip and reads immediately. That is the reason the extraction is worked from three viewpoints, the reason the special cannula is passed again over the surface at the end, and the reason compression discipline in the weeks afterwards is treated as part of the procedure and never as optional advice.
Tell the clinic your full medical history, every medication and supplement you take, any previous surgery on the hip or leg, and any past reaction to anaesthetic. Afterwards, keep the entry point clean and dry, wear the garment for the hours you were given, and call the clinic quickly if pain, redness, discharge, calf tightness or swelling increases after the first few days. A resident medical director is on site through opening hours, so a doctor can look at the leg the same day.
