infantile hemangioma causing pain?

i'm just wondering if anyone has had any experience with infantile hemangioma causing pain or discomfort?

my baby girl is four months old and has one on her back

The doctor said it shouldn't cause any issues It's about the size of a coin and is quite raised).

But she is refusing to sleep on her back and keeps flipping over. She's always arching her back in a lot of pain.

We have been putting it down to reflux, which she's receiving treatment for, but I'm starting to think if it could be this.

Google says it needs to be further down the back to really cause any issues, but I just wonder if anyone's had any experience with them in the middle of the back and any similar symptoms.

Any help appreciated. Thanks.
