I am looking for a toxicologist with creosote poisoning experience that I have ingested?

I have tried to find a toxicologist to answer a lot of questions to do with creosote poisoning which I've ingested some time ago. I'm still having intestinal pain, sort tonsil and throat, and many other symptoms and especially my eyes. all toxicologist I contacted know nothing of coal tar creosote. I'm very concerned about cancer etc which is causing me to be extremely depressed. I had a rash 90 percent of my body for one year Thank you in advance Russ
