(female age 19) Hi a few weeks ago i woke up with bruise like pain in the back of my head just above the neck, and noticed that I have a bump there. i hadn t knocked my head, and i still have the bump it doesn t hurt anymore. It is a rare occasion when i do get headaches however I have had the occasional headache/head presure since then. Also not sure if this links or not but I had a blood test (due to feeling very weak and tired for a few months, thought i had might have a thyroid problem as it runs in my family, and i noticed various signs) done a weak or so after the bump appeared and the results showed that I am low iron. If possible could you please let me know what you think is wrong with my head, and how to help it. Thank you very much for your help. Kind Regards Francesca
