I have a sebaceous cist on my scalp that burst just over a week ago, my doctor said he can see a scab and that it should be fine unless it becomes infected. It is in the very back of my head so I cannot see it but I can feel it, it s quite tender, the scab is still there but it s often sticky. I think the scab is still attached to the gooey white stuff inside and that it s just slowly leaking out or started to leak then got stuck. Should I go back or am I worrying too much??
