Flexion tests are often the next step of the process. By flexing a specific joint for a predetermined amount of time, we can exacerbate lameness. At times it may be necessary to perform nerve blocks to aid in the diagnosis of lameness. In doing so, we are making an area of the leg or a joint numb. If we alleviate the source of pain, the lameness should improve. Once the source of pain is identified, we will frequently pursue radiographs to further assess the problem. Radiographs will also provide us with a reference point should the problem progress or other problems arise.
