I have been having unexplained chronic pain now for about 3-4 months it constantly feels like someone is pouring hot lava all down my neck to my tailbone almost all day long along with soreness and unexplained tiredness, its really taking and emotional and physical and mental toll on me as im getting really depressed and i feel like its never going to end as the cause cannot be found i have tried lots of meds but i think my doc may try me on some narcotic painkillers which im wary about as i dont want to get addicted to them like some people do, im wondering how safe they are if taken ONLY as prescribed no more no less, is it safe to assume i wouldn't get addicted if i take them responsibly?
