Hi, I have been scratching myself for the last two weeks and thread like marks appear on my skin. I consulted a phamacist he told me I have amoeba but after taking medication the problem is not going away . Mostly its on my hands between my legs and at night on my bottom . I am also having sleepless nights even when I am not scratching, could this be the cause and what could be causing the threads, thank u.

What is amoeba?
