question: I am a 41 year old female. In December I received a cortisone shot in my shoulder. At about the same time I started having my period very frequently - i.e. for the last 4 months, I have had my period more often than not. The bleeding is usually not heavy, but definitely increases with heavy exercise. I have the Mirena IUD and usually don t get my period with it so that is especially weird. My pap smear was normal as was the endometrial biospsy. My doctor has given me a 2 week supply of low dosage estrogen but, thus far, that doesn t seem to help. Just recently I have noticed that I am easily bruising and now I have a hard lump on the left back side of my neck. Should I be concerned? Could all these things be related?
