I've recently noticed I have two pretty deep ridges in my skull from front running to top of my head. I've recently had surgery for tibial plateau fracture V
And when in hospital they said I had severe B-12 deficiency, low hemoglobin ( mine was 6), really low BP (77/47) and osteoporosis. .I can't find where any of this would cause these ridges.
When I press on them, kind of tender and get a little light headed
