Chronic Pain is insidious. Medications can produce fatal side effects. Overdoses can happen accidentally, but if future overdose can be prevented, lives can be saved.
Patients may be afraid to go back into the same treatment regimen with the same medications previously given after they survive an overdose of that very substance. One friend survived two, but sadly, not the third.
Too many US Veterans must suffer for years before receiving the correct medication in the correct dosages to help them. Even then, disability income delays creates enough agitation to override the relief afforded by the medications. One such veteran and his family lived in a small leaky camper in the back of a city park in my hometown without utilities until someone took the time to advocate for him.
Another vet, a friend, suffered 30 years before receiving his income, but the medications and side effects killed him in short order.
