Suggest Remedy For Itchy Rashes On Skin

Hi, I contracted an itch on my skin more than a month ago, it started with two bites very close together near my elbow and slowly as the days went by I received more bites on my arm which are very itchy, I thought perhaps it could be fleas or bed bugs, as I have moved home and staying with friends. Eventually the spots spread to my chest, tummy, then slowly spread to my back. I googled rash, to try find out what I had. It looked like Scabies, however, I have no bites on my hands or feet, or between my fingers. I have tried washing with some yellow soap a pharmacist gave me. This did not help alter two weeks of bathing with it. I then went to a doctor, who suggested spregal spray and described Zefroxe 500, which I have now been taking for 3 days. She also gave me Celestamine tablets. No pharmacy had spregal spray, so they made up a cream called Viocfucidin. So far nothing is helping. Could you please shed some light on what this is?
