I have spinal arthritis and i want pain meds but my doctor is not giving them to me? why not?

Ask: Ask your physician. Without knowing your detailed medical history, it is impossible to guess what was your physician's reasoning.

Not indicated?: A condition like "spinal arthritis" would seem like a chronic deal. Opiate pain medications are really not good treatments for chronic pain. What happens is, patients become tolerant to the dose, and then higher and higher doses are needed to do the job. Years go by, and the patients are then on high doses, are still in pain, become opiate dependent with severe withdrawal without the pills.

Long term problems: You are very young to truly have spinal arthritis. Starting a young person on opioid pain pills has been shown to be problematic. People become tolerant to the effects ( more pills are needed) and you can develop what is called opioid induced hyperalgesia. This means the pain pills will cause your pain to actually increase over time. Alternative medications are available. See a specialist
