Cubital tunnel syndrome is the second most common nerve compression syndrome, following carpal tunnel syndrome. It is a condition caused by pressure or stretching of the ulnar nerve as it passes through the cubital tunnel on the inside of the elbow. This nerve controls sensation in the ring and little fingers and helps power some hand muscles, so when it becomes irritated, people may experience numbness, tingling, weakness, or a “pins and needles” feeling in those areas. You can develop cubital tunnel syndrome through repeated bending of the elbow, which may be a result of holding a phone for long periods of time. Over time, these stresses can compress the nerve, leading to worsening symptoms if not addressed. Here are four practical ways to avoid Cubital Tunnel Syndrome as a cellphone user:
1. Keep your elbow more open – Try not to hold your phone with your elbow tightly bent for long periods. A more relaxed, slightly extended arm position reduces pressure on the ulnar nerve.
2. Switch hands frequently – Alternate between your left and right hand when using your phone so one elbow isn’t under constant stress.
3. Use hands-free options – Take advantage of speakerphone, earbuds, or voice commands to minimize the time your arm is held in a fixed position.
4. Avoid leaning on your elbows – Whether sitting at a desk or resting, don’t prop your elbows on hard surfaces while using your phone, as this can compress the nerve over time.
