I was recently diagnosed with scabies, have no idea how I got them, didn t even know what they were. The only possible explanation I have is staying at a hotel a month before I broke out in itchy bumps, or I have a small dog in the house which I just recently doctored for mites. I have went through 3 rounds of permetherin cream, and my doctor just prescribed Stromectol for me, which I took yesterday. I have done everything that I was supposed to, and still feel like I have something crawling on my scalp. I guess my question is....how long does the Stromectol take to get rid of them. I am going crazy over this!!
