I m 55, finished menopause approximately 10 years ago. Noticed in this mornings urination what I thought was a speck or 2 of blood pieces, then didn t notice anything else until this evening. Now see thin layer of blood on tissue with roundness of a flat egg. No blood dripping out. I have been in physical therapy from a vehicle accident for months and within the last 2 weeks have been using the vibrawav (Shake machine) to strengthen my core. Wondering if this could be causing the bleeding or what could possibly be causing this. I do have to urinate often because I am also dieting and required to drink much liquids. I sustained back and neck injuries so both always hurting. I have had some form of IBS for a number of years. Had a gyn check up April 2014 but did not receive notice of any concerns.
