Hi, My mom is 69 yrs old, a left hemiplegia patient for 5.5 yrs now, bed ridden mostly. From past 3 weeks she has uncontrolled loose motions. Thus she is on diaper. My doctor suggested after examination to use siloderm 20 mg for burning sensation around the anal region. However, first of all I needed to know that whether it should be used just externally around the anal region or any rashes, widened exposed skin or inside the anal region??
