Hi, my granny at age 95 is bedridden since end of 2014 due to leg broken, this two days she got anus infection, guess cause of too much watery stool little by little every time and both inner part of her legs near anus both got inflammation, wound nurse only prescribes zinc cream plus stomahesive powder, but does not works very well for her, she looks so painful this two days, what else we can do to help her ease the pain. Please help. Thank you.
