Dear Sir/Ma’am, I have a red patch behind my knee (both knee, where one is a bit more severe) that is red amd very dry (skin feels like stretched or pulled) and itching as well (a desire to scratch it). It is also burning after itching or sometimes even when touched or when water is  applied on it. Relieved when something cold is applied on it. For the time being it is localized and seems to be spreading. Currently I have 2 creams that had been Prescribed to me for a similar issue in the past -1. Momate 2. Fultivate. Can I use anyone of them on this rash or please guide me what could be applied on them Kindly suggest, I will be greatly thankful. Photo attached.
