I am a healthy and fit 47 year old female. One week ago, out of the blue, while sitting at the table, I experienced sharp pains on the left side of my chest...really just one spot. I thought it was gas. Still had pain and difficulty taking a deep breath on Saturday but now my left shoulder and left arm ached. Went to ER Saturday afternoon, EKG showned normal sinus rhythm...after sitting there for 3 hours I left. Symptoms continued through Sunday, not any worse but still there. Monday morning went to cardiologist. Monday afternoon had V-Q scan and chest x-ray...apparently showed nothing because they let me go home. Wednesday had a nuclear stress test and Thursday echocardiogram, (must have been find, no one has contacted me with any results)...It is now one week later and I am feeling better but taking a deep breath is still work. I also noticed that I have not had one single hot flash since this happened seven days ago...I had been having hot flashes three to six times a day...I just want to feel better....made an appt. with gastroenterologist for next week...just frustrated because I am normally the healthiest person ever. Any ideas?
