What causes a hard lump at the top of your spine on right side that only hurts when turning to left?

A hard lump at the top of your spine on the right side that only hurts when turning to the left could be caused by several different conditions. Some possible causes include:

- Muscle strain or sprain: A muscle strain or sprain can occur when the muscles or ligaments in the area are overstretched or torn. This can cause pain, swelling, and bruising.

- Herniated disc: A herniated disc occurs when the soft, inner material of a spinal disc leaks out and presses on a nerve. This can cause pain, numbness, and tingling in the affected area.

- Bone spur: A bone spur is a small, bony growth that can develop on the spine. Bone spurs can sometimes cause pain when they press on nerves or other structures.

- Spinal stenosis: Spinal stenosis is a condition in which the spinal canal narrows, putting pressure on the spinal cord and nerves. This can cause pain, numbness, and tingling in the affected area.

- Tumors: In rare cases, a hard lump at the top of the spine could be a sign of a tumor. Tumors can be either cancerous or non-cancerous.

If you are experiencing a hard lump at the top of your spine that only hurts when turning to the left, it is important to see a doctor to get a proper diagnosis and treatment. The doctor may perform a physical examination, order imaging tests (such as an X-ray or MRI), and/or recommend other diagnostic tests to determine the cause of the lump.
