I went to the doctor the other day for pain in my back that the doctor thinks may be a kidney stone. While there the nurse looked concerned after taking my blood pressure. She said it was very low. 82 over53. She had me lay down and sit and stand. She didn't tell me what it was each time. The doctor came in and said I had postural hypotension. He told me that he thought it might be a little dehydration. I have had it for a few days. I didn't think to bring this up to my doctor but the past two weeks i have been spotting a little. I thought it was done but now every time I have sex I spot and. Does anyone know anything about it? I don't know if they are related. I do have to go for an ultrasound of my abdomen and pelvis to see about the kidney stone thing. Should I bring it up when I go for the ultrasound.
