Parasite in skin. A dog that has fleas!

In September 2016 i had got a mattress and didn't know it had bed bugs a month later I started seeing red itchy spots on my one leg but were bad then in December I ended up going to hospital and the doctor gave me antibiotic for something I never even mentioned something to do with my foot. Maybe currently addicted to meth and heroine but I know it has nothing to do with them. The spots got worse, bigger and inn more spots. Face, I know there's some in my mouth, legs and who else knows where they could be. I went to the emergency 4 more times and they sent me home saying I'm crazy saying it's the drugs. My immune system has been worse then ever cause the last 3 weeks I've been getting cold sweats, hot sweats and have been vomitting even more then I have in my life. When I try to squeeze them out they dig deeper in my face when I try to get the infected area to come out. I think it's bed bugs or also I was in contact more then a few times with a dog that has fleas
