I am a 51 year old Caucasian female medical professional. I used to be a nurse, but now I work in a medical laboratory. I have a history of hyperlipidemia, hypertension, and hypothyroidism, GERD, bipolar disorder with general anxiety disorder and seasonal affective disorder, all well-controlled by medications. However, I also have chronic pain (neck and lower back) not well-controlled by NSAIDs. This past Monday, I did a few chores around the house, over-doing my usual physical activity. I was sore the next day. One curious symptom has continued after my generalized body muscle soreness subsided...I have an achy sensation in my left deltoid, radiating to my collarbone, up my the left side of my neck, and about halfway down my left arm into my bicep muscle. I have no tightness or heaviness in my chest; no dizziness, fatigue, shortness of breath, diaphoresis, or nausea. I ve had episodes of benign PVCs. I ve previously had an EKG, 2-week Holter-Monitor study, and an Echocardiogram, all with normal, healthy results. I know denial is a killer when it comes to cardiac events. Should I be worried?
