Here is a link to buy the sulfur creams and soaps online:
Buy Scabies Soaps and Creams hereI suspect you got luckey and caught it early enough as you do not have many markings and track marks or lesions. The itch is not coming from bugs in your bed but the scabies mites on your skin, your skin is allergic to the scabies mites and their debris (fecal material they drop), so even after you have treated you still may itch during post scabies for a few weeks, the longer you had it for the longer post scabies will take as your skin surfaces all the debris. In post scabies it is also good to use the sulfur soaps and use the creams to spot treat on areas extra itchy or with lesions.
This is what I did and was cured quickly.
Day by Day it should get better though!
