Permanent solution for scabies. This?

Hi, I'm a female and recently married. I've bee ln suffering from scabies from last 2 years. I've consulted so many dermatologists, but everyone was prescribed permite lotion (apply 2times in the span of 20days).I did everything, but when I took medication and all, it's gone. However after 3-4 weeks again it's coming. Again consulting, using same medication and the process repeats. Can anyone please tell me a permanent solution for this? The main problem is my skin is so itching, mainly from bum area to till foot (including under the foot), but everyone is saying it's scabies... I don't know whether it's scabies or something else.. all I feel is.. so irritated itching and yes, there are tiny, micro bums on my skin especially in between fingers and palms (I don't see anywhere in the rest of the body). Please help me out. Thanks in advance.
