I have these symptoms you speak of, and I am nauseated a lot, yesterday I turned grey then really pal and had to be taken to the hospital, they found nothing, vitals all normal. I have a gritty substance that has been showing up on the surface of my hot beverages being served to me by someone close. I have a sample on the end of a fork that I saved in a plastic baggy, but I can not convince anyone to test it. I spoke with doctor and he said they could not and I even had the police called and they said I had to press charges before anything was confirmed and I did not want to do that. They then suggested I go to a labcorp in my area and when I called one they said I had to have papers from police or a doctors order. Can anyone help me? Today I have a strong metallic taste in my mouth, but all I have drank was water that I got myself from the refrigerator. The refrigerator has an ice and water dispenser and that is where I get my water from. I checked the water filter and it is new. What should I do? I refuse to eat anything in this house or accept anything more from the other person. Been very weak, going to attempt to get out of the house and get me some food and bottled water and if I feel better then I know what I suspect to be true and I am moving out. Can anyone tell me where I can get testing done without a doctor's order or police papers please???
