Could lyrica (pregabalin) help me with my scoliosis pain?

Scoliosis. Probably not, you may benefit from physical therapy, back and core strengthening, maybe back brace. If you have bad muscle spasms trigger point injections and or muscle relaxers can help. Bottom line you need a good functional musculoskeletal evaluation.
Maybe. Lyrica (pregabalin) is an anti-seizure medication that is indicated for neuropathic pain. Pain from scoliosis is often secondary to joint pain. If the nerve is irritated from the scoliosis then Lyrica (pregabalin) may be an option.
