Hello, My Mom is 87 and has dementia. For the last several weeks she has developed severe itchiness on her hip (under protective underwear) and underneath her armpit. We are not sure why. It could be the result of an allergic reaction to the underwear but she has been using this product for several years. We are trying to find non synthetic protective underwear/bra but this has been difficult. Any suggestions? She also has diabetes & hypothyroidism. She is taking Levothyroxine, Metformin, Exelon, Namenda, fish oil, iron, Vit. D, cranberry capsule & paxil. Thanks!
