hematuria and fatigue, episode of very high blood pressure.

Hi,
I have had microscopic hematuria for at best the last 3 months. (no dr visits with UA prior). I have since had a cturogram and cystoscopy both of which were "ok". Now im getting pretty sever calf cramps with short distance walks from parking lot to work and overall just feel like garbage. Im afraid i have not been to dr for regular checkup in the past. also have mitral valve prolapse that i take beta blocker for x 30 years. I had an episode of very high blood pressure in Nov which was what took me to the dr. Has since returned to normal and have only taked lisinipril once in the last month. I have a appt at the end of the month but am somewhat concerned that there is osmehting going on. Have had more than normal flutters and dont want to wait till its an issue. If this all sounds like not a big deal waiting wont be an issue but i just dont know and am trying to not avoid and know when to go to the dr.
