Hi, I am 29 years old and a software Engineer. For the past 1 week I am having episodes of dizziness.It starts some 45 minutes after I sit and being work in office,my head feels heavy and goes away after sometime. It occurs during late evenings again, around 7.45 to 8pm and goes away while I leave work, usually 45 mins to 1 hour later. I don’t have any other health issues. Although I have a history of spondylosis of neck. In this case, the pain is local (i.e. only the neck), and doesn’t radiate or there are no symptoms of tingling sensation anywhere else in body. I am now worried what may be causing this. Could you please advise me on what needs to be done. Thanks.
