A diver who helped study marine life after the oil spill in the Gulf of Mexico said he is now experiencing health issues as a result of those dives.

Scott Porter volunteered to collect coral samples and give reporters guided tours after the Deepwater Horizon oil spill.

The 42-year-old said the National Oceanic and Atmospheric Administration told him the waters were safe, yet documents show the agency wouldn't send its own divers.

Porter said that after a few dives, he started experiencing nausea, migraines, rashes and chest pain. He said his equipment was also affected. He is suing BP for that equipment loss.

Porter and other divers have also refused to be part of a national health study.
