I have had dizziness occasionally in the past, with  equilibrium off that gets worse as I get older...was told years ago it was crystals in ear,  but now it happens for longer periods when I look up or bend my neck back, not just when I turn  my neck in bed.  Should I worry if it is really blocked artery in my neck?  How would I know the difference?
Hello, symptoms which you are complaining are typical of cervical spondylitis.  In this condition because of bone formation at neck, nerve and area get compressed, it leads to neck pain and dizziness when neck comes in to certain position.  Treatment is soft cervical collar, tablet squadron and pregabalin.  Also, physiotherapy and traction therapy can help.  I hope this answers your queries. Let me know if I can answer any other question for you. I
