You can also go to a medical University. They have some cool stuff in formaldehyde. They not only will help you, they will even examine it for free. I used My husbands University way back when I first realized I had parasites. He took my specimen and a week later, I was able to use his information to go to the next step. I felt my skin crawling and thought I may have body lice. It turned out to be some parasite.
kellybebby, You also need to trust yourself. It may turn out that you never find a doctor to agree with you. If you educate your self on this subject through research and experience, you need to accept what you have found to be true.
