See medical doctor: Dental local anesthetic injections DO NOT cause weakness and numbing of arms and legs. Something else is going on. It might be anxiety or another medical condition, but what you describe is not directly caused by the injections you had. Please call your medical doctor for an evaluation ASAP.

? CVA: Agree that the local injections have nothing to do with your problems in the right arm and leg. You need to have this looked at ASAP, as there is a possibility you may be experiencing a stroke, or other focal neurological event. Best you visit nearby Emerg Dept and get evaluated.

ER, Now: Local anesthetic will not cause systemic weakness/numbing. Concern is CVA (Stroke). Please have someone take you (do NOT drive yourself), or call ambulance, to ER immediately.
