My husband is a Vietnam veteran. About five years ago after being in great health developed asthma and severe allergies. He also has developed these rashes that appear to come from nowhere. His VA Dr's have no answers as to why he has these problems. Our grandson has asthma too. I have not seen any real evidence that his problems could be from being exposed to the herbicide but am planning on discussing this with his VA Dr later this month. Has anyone else had problems like this? It appears unlikely that after all these years agent orange could be the cause but I will continue to research this.
