I am not sure if this was a one time occurrence or has happened in a recurrent
fashion but varicose veins, PAD are conditions that are not fleeting in nature.
I think an isolated episode without antecedent symptoms of chest pain, shortness of breath facial swelling, arm pain or any abnormal upper body symptom should not be bothersome but if this were to happen again or you have any of the symptoms that I have listed, you should certainly seek medical help.
