Do not rely on opiates as a major way to reduce chronic pain! While there are individuals who need to be on opiates for some time, realize that pain management teams are reducing or eliminating opiate prescriptions due to the exponential inctease of deaths from opiate overdoses. Even those Anasthesiologists who identify themselves as Medical Pain Specialists, and do trigger point injections, nerve blockers, neural ablations (nerve burning) and insert Transdermal Electronic Nerve Stimulators (Internal TENS units) are veering away from prescribing opiates.
There are other medicines that can help with pain. These include NSAIDS like Aspirin, Ibuprofren and Naproxin, Acetometiphren, Serotonine Neurepinephrine Reuptake Inhibitors (SNRIs), like Cymbalta and Effexor and some older Tricyclic Antidepressants (TCAs) like Amitryptaline. Otherwise, it is best to consider multiple strategies to reducing pain other than simply taking medications.
