A drug usually used for opioid addiction—low-dose naltrexone—might be a game-changer for Long COVID. Researchers found it helps 'fix' faulty cell doors (ion channels) in Long COVID patients, letting cells work properly again. This could mean better immune response, less pain, and improved brain function for millions still struggling with symptoms. Clinical trials are underway, but this could be the breakthrough so many have been waiting for! #LongCOVID #HealthNews #MedicalBreakthrough #Naltrexone #ScienceUpdate #Health
