[|Human|] I have a scar on my sacrum where a lipoma was removed over 8 years ago. It is horizontal and about an inch in length. It is itching terribly and has two raised, red bumps on the scar tissue itself. I am fit and have not gained any weight. What could be the cause of this and should I be concerned?
[|AI|]  Welcome to Chat Doctor .1. It could be re-growth, reoccurrence if the lipoma again (its possible in many cases)2. Or an infection in the scar area with internal collection causing lumpy feeling - generally with pain.3. Yes it should be concerned, you see your GP and get the area scanned with ultrasound - it will help us to assess the nature of the lump, its source and extensions.4.Accordingly, the treatment can be planned - if lipomatous - just monitoring is enough, removal upon discomfort.5. Suggest do not scratch the area, as it may get complicated. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
