Pressure: The nerve has little padding over it – direct pressure can press on the nerve Stretching: Keeping the elbow bent for a long time can stretch the nerve – this can happen during sleep Anatomy: Sometimes the nerve does not stay in place and snaps back and forth over a bony bump as the elbow moves – this can irritate the nerve. Abnormal swellings within the cubital tunnel may also press on the nerve
Avoid actions that cause symptoms such as pressure/leaning on the elbow
