Most likely, you have either ruptured a disc in your spine or caused a muscle spasm that is pulling your spine out of alignment and now pressing against a nerve. The nausea and dizziness
are often caused by anxiety
that immediately sets in when a person experiences intense pain - this type of reaction to pain is completely normal.
But on the other hand if you had chest pain
(retrosternal) induced by anxiety/excitement,and the pain remained for a shorter duration and relieved on rest or taking medication (nitroglycerin
) then possibly it could be an anginal attack.In such case you must do an ECG done.
