Hi..I got a neck strain..after i completed workout and hours later a sudden muscle spasm in back of neck and then it was paining for next 2 days.. I could move neck left right with slight pain .now I am putting head pad on neck for 10 min and it relieves the pain. after 1 week hardly  I have any pain there but sometime I feel I have some vomiting sensation, is it possible that a neck strain might cause vomiting sensation, I measured my BP and its 127/84 which seems ok to  me.
Yes neck pain if  occurring due to cervical spondylitis can lead to nausea and vomiting. Bp is fine.
