Ive got a swollen sore lump on the back of my neck near spine. it only hurts when i touch it. but had really weird headache yeserday?

It's important to see a doctor to evaluate the lump on your neck and determine its cause. Several potential causes of a swollen, sore lump on the back of the neck near the spine include:

- Swollen lymph nodes: Lymph nodes are small, bean-shaped glands located throughout the body that help fight infection. When the body is fighting an infection, the lymph nodes can swell.

- Lipoma: A lipoma is a benign, fatty tumor that can grow anywhere in the body. Lipomas are usually soft, movable, and painless.

- Muscle strain: A muscle strain can occur when a muscle is overstretched or torn. Muscle strains can cause pain, swelling, and tenderness.

- Herniated disc: A herniated disc occurs when the soft, inner material of a spinal disc leaks out and puts pressure on the surrounding nerves. Herniated discs can cause pain, numbness, and tingling in the neck, shoulders, and arms.

A sudden, severe headache is also a concerning symptom. Several potential causes of a sudden, severe headache include:

- Aneurysm: An aneurysm is a bulge in a blood vessel. When an aneurysm ruptures, it can cause a sudden, severe headache.

- Meningitis: Meningitis is an infection of the membranes that line the brain and spinal cord. Meningitis can cause a sudden, severe headache, fever, stiff neck, and nausea.

- Stroke: A stroke occurs when the blood supply to the brain is interrupted. Strokes can cause a sudden, severe headache, weakness, and difficulty speaking.

If you are experiencing a sudden, severe headache, it is important to seek medical attention immediately.

If the lump on your neck is painful, swollen, or tender, it's important to see a doctor to get it evaluated. The doctor may recommend imaging tests, such as an ultrasound or MRI, to determine the cause of the lump.
