<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello doctor, For a month I have been suffering from a wide range of symptoms. Anything including, bad headaches, pressure and burning sensations in my brain, taste of blood in my mouth, off balance and dizzy, fatigue, and now cold feet and hands constantly. I m nervous and scared. What is going on.. I play soccer and I am known to head the ball an awful lot.. My Dr says it s nothing but post concussion syndrome. I believe its more than that...  <response>: Hello! Welcome on Chat Doctor ! Your symptoms could be related to the concussion or a metabolic disorder. For this reason, I recommend performing some tests: -a resting ECG-blood electrolytes- complete blood count-thyroid hormone levels-vitamin D and vitamin B12 plasma levels. If all the above tests result normal, you should consider anxiety as the main cause of your complaints. Your headaches are typical of tension type headache which is a benign type of headache triggered by psychological stress. You should discuss with your GP about the above tests. Hope you will find this answer helpful! Best wishes,
