What Do Rashes On Elbow,leg,foot And Nose Of A Toddler Indicate?

Question: My son 2.6 yrs old has rashes on his elbow,leg,foot and little bit under mouth & nose. The rashes are sever in elbow. I found it getting more severe on last Saturday. Hence immediately I rushed to my doctor's clinic and he is out of station for next 1 week. Hence alternatively I went to nearby clinic where i visited a pedeatrician who suspected it to be either due to insect bite or scabies. Hence given medicine for few days to control the rashes - Permite 5 cream, Calosoft lotion, Syr. Atarex. Saturday nigh he was feeling very itchy in the legs. But sunday night it is improved and itching has come down. His weight is average 12.5. Last 2 days he is not eating properly and I feel he might have lost some weight also. Though itching has come down, his elbow is having quite a lot blisters. How long will it take to completely cure. Any precautions we need to follow.

Please advice whether the current medication is good or need to visit the doctor again for further treatment.
