My mother was admitted into Kaiser permanente due to a woman's yeast infection along with a bed sore that got infected. I had been trying to see my mom for the last year and a half when I finally talked to my brother he told me that I had to make an appointment with him. He kept making excuses as to why I couldn't see her , the day my wife called an attorney is the day he called me and said she was having a better day and I could see her at 5:30 pm. So we went to see her at her house and she was in bed. A week later is when he called me and told me he was taking her to the Dr. I met him there and saw her and that is when I found out about her physical state. The nurse told me that all of this could have been prevented. And that is the whole reason for my suspicion ( concern) because why did he prevent me from knowing about her condition? What was really going on ? Was he abusing her? I could have helped take care of her! Now there isn't too much I can do.
To add, being a caregiver is hard work, caring for someone bedridden and incontinent is exponentially harder. Perhaps he was doing his best or perhaps he was negligent, but there is a long way from being a lousy caregiver to being an abuser.
If you feel you have valid concerns about abuse, contact the police or Adult Protective Services. But be aware, if your allegations are unfounded, you will have opened up a huge can of nasty worms.
What do you mean by a "woman's " yeast infection? Vaginal, breast? As pointed out above, they are not usually sexually transmitted.
If you and your brother are going to successfully care for your mom, you need to talk to each other and both gain an understanding of her medical conditions.
