Informative website symptoms and conditions

I am a 55 year old female. I had a heart attack in July -08. I had a stent placed. Since then I have been on Plavix, Lopressor, Lisinopril and Lipitor. I have been back to the Hospital 2 times since then. The first time they found nothing. The second time I had to have another stent place because the first one didn't work. This last time they did another catheter and found nothing. I have episodes every couple days of Light headedness, heart pounding, stomach upset, confusion , really bad burping and sometimes diarrhea. I am at my wits end. I have lost 30 lbs and am weak most of the time. I was very active before all this and can't get back on my feet. When I ask about the medicines, the doctors say I don't think it's that. Someone please help!

Has anyone out there had an increase in urination? I started Yaz in Feb. and since then I've been peeing like a race horse. My OBY said it was probably an overactive bladder, typical for a peri-menopausal woman. I had tests for bladder infections and they read negative. I was in the middle of relocating my family across many miles and I just put up with the symptoms. Now I find out there is microscopic blood in my urine and I am scheduled for a slew of tests probing for tumors, cancers, polyps, etc. in my bladder and kidneys. My Dad had bladder cancer so I'm pretty scared. However, I am starting to wonder if there is a Yaz connection. I hate the thought of returning to periods where I couldn't leave the house because I was bleeding so much but all the risks here are scaring me. I don't have an OBY here yet but assuming I am not harboring cancer or an other disease (i.e., kidney stones) I think I'll go off Yaz. I already have horrible migraines and acne so I'm wondering if it will all get worse. My headaches are the same (2-3 times a month) with Yaz and my skin is better. It's been pretty good for water weight but as I said, I am in the bathroom way too much.
