This program aired in my area last night. I think the title was "Eating me alive". They had different people telling about their experiences along with actual footage of the parasites and what they did to get rid of them.
Very interesting, but probably not for the squeamish. Most were gotten in foreign countries, although a couple from eating food that had the parasites (or eggs that later hatched in the body). A couple had to be surgically removed.
One guy was watching a ball game when his eye started itching. He went to the bathroom and looked in the mirror to see this tiny white worm looking thing traveling across his iris. He went to the doctor, but the worm had disappeared before he got there. Another was sitting on the toilet when he felt something strange. He found this long thing protruding from his body. He called his wife and together they tried pulling it out. I don't remember how many feet came out, but it wouldn't all come out, so his wife got some scissors and cut it close to the body. The remainder retracted into his body. After medicating the worm was killed and then it came out.
Some of these people were near death, and some contracted diseases like Elephantiasis, or malaria etc.
It will probably air again, watch for it. Wished I had taped the show.
