Hi...I was just reading online that segmental hemangiomas can have a growth phase that is longer than a typical hemanigioma...is a segmental hemangioma the same thing as a compound hemangioma? Maybe that's why it's taking longer? I would also double check with one of the experts on here. I'm sure they will be able to help you and give you more peace of mind about the treatment plan. Good luck with everything! I'm sure it feels like it's been going on forever, but I bet you are on the verge of turning the corner. Once we turned that corner and my daughter's finally started to involute without medication, it's like I could barely believe my eyes. I was like, "Wow! It really does fade eventually!"
