Can neck tension cause a constant weird lightheaded feeling for 24/7 for 5 yrs sometimes swaying feeling eyes funny drs tell me anxiety i worry it's m?

M?: 5 yrs of constant tension - truer if you know some is in your neck - certainly can result in balance/vision disturbances. Proper oxygen, blood and nerve impulse supply, etc. is thrown off balance so you are too. Ask your therapist to target anxiety mgmt or for a referral to a CBT anxiety specialist. I'm not sure what you worry it may be, but worry will hurt, not help. Get a full physical exam too.
