Hi, My grandmother have a kind of skin issues at her back. She complains that it is irritating, some times very itchy and some times burning sensation kindof. Now it is increasing with the onset of winters. First we thought it is a dry skin and then it is not an even skin anymore. Kind of bumpy skin with reddish and brownish bumps all over her back especially on the left back. Have cetrizine by consulting OTC but of no help. Regularly keeping it lubricated by giving Vaseline but it does not help the burning and itchy sensation. Nb: she cannot walk much hence not been able to go the doctor. Nb: Please refer to the attached picture for your reference.
