[|Human|] A few times, (including today) I have head rush upon standing, and sudden difficulty focusing on reading (spotty), followed by mild headache. I ve had sore back left side of my neck for several months (not sure if it is related to the above problems). What could be causing this?
[|AI|]  Dear serve understand your concerns went through your details. Sore back left side of your neck for several months could be associated with stress. Do you have stress ? Sudden rush of blood to head is common when you stand up suddenly. But in your case, this can also be related to your stress, if you have it. Difficulty focusing, mild headache etc. are also symptoms of stress. Please provide the details of general lifestyle and office life. I suggest stress management.
