Progress in osteoarthritis pain relief signaled by new research

A new way to potentially block the chronic and often debilitating pain affecting osteoarthritis sufferers has been uncovered by researchers. Currently, people experiencing the severe pain associated with OA are offered pain relieving drugs such as steroid injections and non-steroidal anti-inflammatory drugs, which work by reducing inflammation. However, some of these drugs can be associated with severe side-effects that limit their use. In a new study, scientists studied a protein (‘receptor’) called TRPV1, which is produced by nerve cells in the human body that are responsive to pain, including those that respond to stimulation of joints.
