Took aleve, (naproxen) my heart started racing,the side of my neck felt weird and it came back just my neck thing then i started to get lightheaded, not as bad n?

Possible allergy: While this isn't a typical allergic reaction, it still falls within the possible symptoms that one might get. If this persists you should see a doctor. If you notice any tongue or lip swelling or have any issues breathing seek help immediately. I would be careful taking Aleve (naproxen) again, until you have a better sense about what is going on. Best of luck.
