Chronic pain can be tricky and difficult to treat. But the discovery of a gene that regulates persistent pain could help.

Scientists have known about the HCN2 gene, found in nerve endings, for several years. But they didn't fully understand it's role in regulating pain until now.

The research in the journal Science finds that removing or blocking this gene eliminates neuropathic pain without affecting normal pain sensation.

Scientists from Cambridge University say the discovery should help drug researchers in the search for more effective targeted pain killing medicines.
