I had pounding palpitations in my chest Friday afternoon, TIA symptoms on Saturday afternoon, Monday night I woke up at 12am with my chest pounding, Wednesday I had an aura migraine and pins and needles in my left foot/toe, Thursday my toe is numb and having spasm/palpitation sensations in my left leg - about a hand length up from my ankle bone - should I be concerned????? I have been diagnosed with Patent Foramen Ovulae, my blood shunts in reverse when under pressure (bubble test) and I am now taking low dose aspirin.
