Judging by a lot of reading i have been doing, it seems to be nothing but i discovered a indentation to the left of my hair parting(center), about 2 inches long and 1/4 wide. Just appeared today. Im slightly freaking out because I m going through a lot of medical issues. Have suffered joint issues nearly all my life, I m 31 y/o, found out i have hypermobility syndrome (still getting other tests to confirm or diagnose with something else), and just found out i have aortic dilation. I have adhd, anxiety, and stress like crazy at this point. Will this indent go away? How did it get there? Is it a part of my medical issues? Should i see my doctor about it?
