My Mother 72 years heavy weight and diabetic (on insulin injections) underwent Breast cancer surgery about 5 month back. The surgery went well but since then she has been having itching in the back- which was not there before with all her medicines. Have consulted skin specialists but all creams etc. Given provide only partial relief. Skin does not seems to show any significant signs of rashes etc. Other approaches like oil etc. Again provide partial relief only. The additional medicine prescribed was Arimidex 1mg but the itching problem started even before this was added. Looking for any advise on what to do and whom to consult.
