Why do you get pins and needles in right side of head?

There are many possible causes for pins and needles (paresthesia) on the right side of the head, ranging from harmless to more serious underlying medical conditions. Here are some potential causes:

Temporomandibular joint (TMJ) disorders: Issues with the joint that connects your jaw to your skull can cause pressure on the surrounding nerves, leading to pins and needles in the head and face.

Trigeminal neuralgia: This condition is characterized by sharp, stabbing pain on one side of the face, including the scalp. It is caused by irritation or compression of the trigeminal nerve, which provides sensation to the face.

Migraines: Pins and needles can sometimes be a symptom of a migraine headache. It's often accompanied by other symptoms such as intense headache, nausea, and sensitivity to light and sound.

Cervical spondylosis: This is a condition where the vertebrae in the neck become narrowed, putting pressure on the spinal cord and nerves. It can lead to various symptoms, including pins and needles in the head, neck, and arms.

Herniated disc: A herniated or slipped disc in the cervical spine can press on the nerves and cause numbness, tingling, or pins and needles in the head and neck.

Multiple sclerosis (MS): MS is a neurological condition that affects the brain and spinal cord. It can cause a variety of symptoms, including pins and needles, numbness, and other sensory disturbances.

Brain tumor: In rare cases, pins and needles on the right side of the head could be a sign of a brain tumor that is affecting the surrounding nerves.

It's important to seek medical attention, especially if the pins and needles are accompanied by other concerning symptoms, sudden onset, or do not resolve within a few days. A healthcare professional can properly evaluate your condition and determine the appropriate course of treatment.
