My father has diabetes since 2019. He has minor heart blockage. Some kind of skin infection has taken place all over his body... probably after he started the medicines. Even after visiting dermatologist quite a few times we did not get satisfactory result. However before covid we had it almost under control since there was minor itching but no pus come out of them. Recently he had covid with pneumonia of moderate severity. But after it the rashes are reviving with new heads. He has weakness as well. Please suggest what do to. He had fasting sugar of 140 a few days back. Please suggest me something for the skin rash and weakness
