I recently had Scabies, and think I ve gotten rid of it, however, when my mucus drains into the back of my throat, it gets stuck, not matter if i drink something afterwards. when i try to spit it up, it s simply clear mucus with pieces of white stuff. I ve lost my appetite, and have a headache. I m nauseous and slightly dizzy as well. What is going on? could is be the Scabies still?
