Occipital neuralgia. Occipital neuralgia (ON) is a painful condition affecting the posterior head in the distributions of the greater occipital nerve (GON), lesser occipital nerve (LON), third occipital nerve (TON), or a combination of the three. It is paroxysmal, lasting from seconds to minutes, and often consists of lancinating pain that ...
Although astigmatism may be asymptomatic, higher degrees of astigmatism may cause symptoms such as blurred vision, double vision, squinting, eye strain, fatigue, or headaches. [7] Some research has pointed to the link between astigmatism and higher prevalence of migraine headaches. [8]
Scintillating scotoma is a common visual aura that was first described by 19th-century physician Hubert Airy (1838–1903). Originating from the brain, it may precede a migraine headache, but can also occur acephalgically (without headache), also known as visual migraine or migraine aura. [ 4]
Sciatica is known as an extremely painful symptom. Nerve glides are a common option for sciatica due to their cost-effectiveness. After performing nerve glides, the Numeric Pain Rating Score (NPRS) rated by patients improved, indicating a reduction in the pain. The nerve glide reduces acute sciatica and improves the range of motion of the hip.
The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.
Neurogenic claudication ( NC ), also known as pseudoclaudication, is the most common symptom of lumbar spinal stenosis (LSS) and describes intermittent leg pain from impingement of the nerves emanating from the spinal cord. [ 1][ 2] Neurogenic means that the problem originates within the nervous system. Claudication, from Latin claudicare 'to ...
Piriformis syndrome is a condition which is believed to result from nerve compression at the sciatic nerve by the piriformis muscle. [ 2][ 5] It is a specific case of deep gluteal syndrome. [ 6] The largest and most bulky nerve in the human body is the sciatic nerve. Starting at its origin it is 2 cm wide and 0.5 cm thick.
As deep gluteal syndrome is defined as entrapment of the sciatic nerve, patients will have pain along the distribution of the nerve, also known as sciatica. [6] These general sciatica symptoms include unilateral, though sometimes bilateral, radiating pain or dysthesias in the affected legs. [6] [2] There may also be abnormal reflexes or ...
