Brief Answer: Chronic fatigue syndrome perhaps... Detailed Answer: Hi, To be XXXXXXX it is difficult to name the exact cause when there are multiple and chronic symptoms without a close physical exam and relevant investigations. However the network of symptoms described by you closely mimic chronic fatigue syndrome. Off course this is a condition that should be confirmed after we exclude all other possible reasons. Concussion symptoms rarely last for more than 6 months. It is definitely less likely to be the cause of all the listed symptoms. If I were to be your treating doctor, I would order tests to rule out metabolic condition - diabetes, thyroid disorder, anemia and co-existing vitamin deficiency especially vitamin b12 deficiency. Though I do not mean to upset you, but I would also consider the possibility of depression as my next possibility. Vitamin D at 17 is marginally low. It may be related to nutritional deficiency (if you have not been eating well) or may be related to perimenopause. I would start you on vitamin D supplements - granules once a week for 4 weeks and repeat the test after a month. I wouldn't want to comment about ESR as it is a non specific marker. In short, it is possible that your symptoms could be due to chronic fatigue syndrome. Visit your physician to exclude other possibilities as described above. Hope this helps. Let me know if you need clarifications. Regards

Brief Answer: No, head injury is unrelated to vitamin D low.. Detailed Answer: Hi, Concussion is in no way linked to low vitamin D level. As I described in my previous reply low level is due to vitamin deficiency, lack of sun exposure and to some extent related to perimenopausal age. It can be corrected without any concerns. Hope this helps. Best Regards
