Post menopausal bleeding. I spotted for almost a week and it is gone now but I have not had a period in 5 - 6 years. Is this something to be concerned about or could it just be a fluke? I did have a medical procedure about 4 weeks prior to this called a capsular dialation of my left shoulder for frozen shoulder and was under "twighlight" anesthesia for that procedure. Could the anesthesia been a trigger?
