Hi my dd is 7 and has HFA the issue isn't ASD related though. When born she held her L arm strange always struggled getting arms in tops also born with DDH both hips treated with pavlik harness. Then her arm started changing colour il try to describe you see the viens through the skin change from purple red blue then White which then leaves her arm either White rashy or red racy. She's had loads of tests done when a baby and she's starting to notice it more now and get upset about it and it tingled when it happens And apparently they've discharged her as they didn't know what it was . I thought since mums are gods you may have an idea what it could be. Thanks in advance
