| | The sensations experienced in nerve pain are unlike anything else, ranging from the odd, “buzzing” sensation doctors call paresthesia that you might feel from a minor case of peripheral nerve damage, to the devastating complex, bizarre burning called dysesthesia that results from more severe nerve injury. | | | However, when we’re dealing with pain caused by nerve injury, such as central pain or peripheral neuropathy, the normal concept of pain is thrown out the window. | | | Evoked pain from peripheral nerve injury is instantaneous, but time is required for temporal summation before evocation of pain from central origin occurs. |
