S.M.
If i was you i would go to a different doctor and get another opionion cause that is just not normal. i had a problem before and my one doctor keep saying i had a bladder infection and it just wouldn't go away so a nurse at my work told me to go see a doctor she knew and i am glad i did cause i never had a bladder infection in the first place i had a cevical problem and he caught it in time before it became cancer. now please don't think you have that but doctors are human just like us they can miss things there not perfect it is always good to get a second opionion.
blessings to you and your family
