I had a lipoma on my forehead removed by a plas. surgeon about 6 weeks ago. The incision is within my hairline. The swelling has never completely gone done. It has improved dramatically, but there's still quite a bit and it's mainly along the incision. It's not painful or infected. I also do not believe it to be any gathering of fluid. I'm simply unsure why the swelling won't go down. I've used ice packs, warm compresses, taken anti-inflammatory meds, and nothing seems to be helping.
