What Causes Severe Weight Gain While On Vesicare And Trandate?

Hello Doctor. I am a 52 year old menopausal woman. I had a hysterectomy over 2 years ago. I was on HRT but have been off that for some months. I take trandate (supposedly to address my hot flushes and sweats, but it does not) , Endep to assist with sleep (again, it is not terribly effective) and Vesicare to assist with incontinence (which does help). In the last six months I have gained a large amount of weight (approx 14 kilos) and have low platelet and low white blood cell counts. In the last few days I have have severe groin pain. My doctor has suggested just monitoring my blood, which makes sense as I am gaining not losing weight and I do not have any illnesses. I get fatigued easily and don t have large energy levels. I would like to exercise, but I ache all over after walking for a very short period of time.Any suggestions?Thank you ,Jo
