My 12 year old daughter has suddenly developed some odd marks along her spine area around the T10 to lumbar region, (in the last 2 days). She has also been having back pain for about a month, lower right lumbar...what could the marks be and is it related to her back pain that she developed during cross country training? (She s thin/lanky)
