Hi, last night i believe i had a panic attack, ive had them in the past, there was nothing to bring it on, i was just laying on couch and my heart started racing, which in turn caused me to walk around, etc... iam over weight, have hypothyroid, high cholesterol and blood pressure. i take medications for all three. i slept for an hour and the middle of my chest was sweaty but no where else on my body...weird huh..lol anyways that s my story. im walking around today and feel ok. Last night scared me enough to make an appointment with doctor to get a stress test done.
