Tight occipital muscles, also known as suboccipital muscles, are located at the base of the skull where it meets the neck. These muscles are responsible for maintaining posture and facilitating movement between the skull and top vertebrae. Structural and functional changes in these muscles can induce dizziness, clinically known as cervicogenic dizziness or cervical vertigo. This condition is characterized by symptoms such as neck pain, stiffness, lightheadedness, and headaches. Cervicogenic dizziness is often treated with physical therapy, vestibular therapy, and medication.

What You'll Learn
Cervicogenic dizziness
The cervical spine plays a crucial role in balance, and cervicogenic dizziness is believed to be caused by a disturbance to it or the surrounding tissue. The cervical spine contains 50% of all nerves related to the body's inner workings, and the muscles surrounding it are essential for movement and communication between the body and brain. Structural and functional changes to the cervical spine, such as those caused by whiplash or a concussion, can lead to cervicogenic dizziness.
The treatment for cervicogenic dizziness typically involves a neurologist, a doctor specializing in brain, spinal cord, and nerve diseases. Physical therapy is often recommended to strengthen neck muscles and reduce pressure on cervical discs. Vestibular therapy, consisting of tailored exercises, is also suggested to address the dizziness specifically. In some cases, medication may be prescribed to manage symptoms, including muscle relaxants, pain relievers, and drugs to reduce dizziness.
The precise relationship between neck pain and dizziness has been a subject of debate since the 1950s. While there is no single test for cervicogenic dizziness, a thorough medical history and evaluation are necessary due to the similarity of symptoms with other conditions. A comprehensive assessment of the neck is also crucial, and clinicians may utilize various tests to determine if dizziness originates from injuries to the vestibular system, brain, neck, or a combination of these factors.

Cervical vertigo
The symptoms of cervical vertigo vary from person to person. Most people describe a lightheaded or "floating" sensation rather than a spinning feeling, which is more typical of other types of vertigo. People with cervical vertigo may also experience trouble walking or standing, as the sensations of movement do not match what the body is doing. Other symptoms include vision issues, nausea, and lack of coordination.
The key to treating cervical vertigo is to identify the underlying cause and address it directly. For example, if the cause is cervical disc degeneration, treatments for that specific condition would be the main course of action. If the cause is whiplash injury, NSAIDs, muscle relaxants, physical therapy, and chiropractic care may be useful. Physical therapy exercises can also help keep the neck muscles strong, reducing the risk of developing cervical vertigo.
It is important to note that cervical vertigo symptoms can appear months or even years after a traumatic incident. Additionally, cervicogenic dizziness can mimic other more serious health conditions, so prompt diagnosis and treatment are crucial.

Occipital neuralgia
Dizziness can be caused by several factors, including dysfunction of the vestibular or non-vestibular systems. While the former is well-understood, cervicogenic dizziness, caused by abnormal sensory input, is less known. Structural and functional changes to the suboccipital muscles, which act as stabilizers and controllers of the head, can induce dizziness. Poor head posture can cause postural sway, transmitting abnormal stimulations to cervical structures and leading to dizziness.
Now, onto occipital neuralgia. Occipital neuralgia is a condition in which the occipital nerves, which run through the scalp, are injured, inflamed, or compressed. It can be caused by a pinched nerve root in the neck, prior injury or surgery to the scalp or skull, or "tight" muscles at the back of the head that entrap the nerves. Occipital neuralgia can be difficult to diagnose due to its similarities with migraines and other headache disorders. A physical examination and neurological exam are typically conducted, and if inconclusive, further imaging, such as an MRI, may be ordered. Treatment options include medications, steroid injections, botulinum toxin injections, physical therapy, massage therapy, and occipital nerve stimulation, a minimally invasive surgical procedure.

Structural changes to the head and neck
Poor head posture can induce postural sway, transmitting abnormal stimulations to cervical structures and causing dizziness. Structural changes to the upper cervical spine, such as atlanto-occipital and atlanto-axial joints, are more closely associated with dizziness than changes in the lower cervical spine. This is because the upper cervical spine contains a significant proportion of cervical proprioceptors, which are essential for proprioception, the sense of self-movement and body position.
Abnormal stimulations to the cervical structures can cause dizziness by disrupting the integration of sensory inputs from the vestibular organs, visual and auditory cues, resulting in a sensory mismatch. This sensory mismatch can manifest as dizziness, pain, lightheadedness, and headaches.
Additionally, tight suboccipital muscles can lead to occipital neuralgia, a headache disorder affecting the occipital nerves. While the pain may be brief, it can also become chronic and intense, requiring surgery if non-surgical treatments are ineffective.

Poor head posture
The suboccipital muscles, located in the deepest layer of the upper cervical spine, act as stabilisers and controllers of the head. Structural and functional changes to these muscles can induce dizziness. Forward head posture, where the lower neck is flexed forward and the upper neck is hyperextended, can cause hyperflexion of the lower cervical spine and hyperextension of the upper cervical spine. This can lead to reduced blood flow to the brain and ears, causing dizziness and brain fog.
Additionally, forward head posture can be a result of improper ergonomics at a workstation, such as using a phone, laptop, or tablet with a screen below chin height. Straining forward while working on these devices can lead to a relative forward head posture, which can contribute to dizziness.
If you are experiencing dizziness due to poor head posture, physical therapy exercises can help strengthen the neck muscles, reduce pressure on the cervical disks, and decrease the risk of developing cervical vertigo. It is important to address forward head posture as soon as possible, as it can be a huge obstacle to recovery from dizziness.
