I have things crawling in my body, up and down my spin, back of my throat, in my nose, in my testicles and my anus!!! It feels like spiders and sometimes they are relentless, what are they????? Is it alL in my head..... It feels real and they are definitely getting stronger! Can you help or suggest a tonic............ They havE made my life a living hell for nearly Two years ....... I'm at my witts end, they only come out at night, when my body is relaxed and I sometimes don't get any sleep...... Can you help please?
