When one mom took to a medical platform called CrowdMed, her son Joseph was in desperate need of help.
"My son feels like an old man," she wrote. "He suffers from constant, debilitating fatigue, painful body aches ... he feels like he's dying."
After submitting his case to the site, more than 40 "medical detectives" — medical experts from around the world — took it on. They came to the consensus that he most likely had Lyme disease, even though that had previously been ruled out by his physicians following negative test results.
