My sibling is on a mission and recently became unwell. When he told the mission president (who is not a medical professional), he was given something from a pharmacy. He had a reaction to this medication. He became cyanotic and extremely anxious because he felt terrible. His skin was blue and he had no idea what was going on so he contacted ME. They never took him to a hospital. They never referred him to a doctor.
Then, after 3 days of vomiting, they had him out laying cement at a member's house. I wish there was a safer why to address these concerns with the healthcare of missionaries. When they have to run these concerns through the Mission President, it can be dangerous and harmful if it is not addressed appropriately by a medical professional.
