169 Possible Causes for Paresthesia, Thenar Muscle Atrophy

  • Carpal Tunnel Syndrome

    Carpal tunnel syndrome (CTS) is a common and sometimes challenging condition, which causes pain; paresthesia; tingling of the thumb, index and long fingers; and even thenar[] At the six-month follow-up examination, the patient experienced relief from numbness and improvement in thenar muscle atrophy was noted.[] Tinel's sign is the induction of paresthesias by tapping over the site of the median nerve at the wrist.[]

  • Median Neuropathy

    […] of the nerve at the carpal tunnel (the onset of paresthesia indicates a positive Tinel's sign).[] muscle atrophy may occur.[] Signs include a positive Tinel's sign at the wrist (tingling in median nerve distribution on percussion over ventral wrist), positive Phalen's sign (similar findings within[]

  • Cervical Spondylosis

    Paresthesia may cause numbness, tingling, or a pinprick sensation.[] The patient may experience shocks (paresthesia) in hands and legs because of nerve compression and lack of blood flow.[] […] groups, especially in the extremities poor or pathologic tandem gait atrophy of the hand’s thenar prominence (the fleshy fat pad just superior to the thumb on the ventral[]

  • Cervical Herniated Disc

    Neck pain Arm pain, tingling or numbness that radiates down the arm and possibly into the hand Muscle weakness Diagnosis Diagnosing a herniated nucleus pulposus begins with[] Patients may be asymptomatic, but nerve root compression can give rise to symptoms such as pain, paresthesia, and neck stiffness.[] […] herniation includes neck and radiating arm pain, though symptoms can include any of the following: Neck pain Radiating shoulder or arm pain that may extend into the hand Tingling[]

  • Cervical Myelopathy

    The patient's complaint was a one-year history of intermittent bilateral lower buttock paresthesias radiating to the bilateral posterior thighs.[] […] groups, especially in the extremities poor or pathologic tandem gait atrophy of the hand’s thenar prominence (the fleshy fat pad just superior to the thumb on the ventral[] While non-neurological symptoms improved, she developed paresthesias in her hands and feet and progressive pain in her legs.[]

  • Cervical Spinal Cord Tumor

    Case presentation A 50-year-old African-American woman presented with a 4-month history of numbness, paresthesias, and mild left-hand weakness.[] Initial symptoms included occipital pain, glove-type numbness, and paresthesia of the upper extremities. In all three cases, myelopathic signs preceded radicular signs.[] Clinically, they sought medical care because of progressive paresthesias or urinary incontinence caused by a nodular, fairly circumscribed intraspinal tumor of the cervical[]

  • Brachial Plexus Neuropathy

    Numbness or paresthesias (71%, 52-86%) and pain (43%, 25-62%) were the most prominent symptoms, while the most prominent objective signs were decreased or absent muscle stretch[] Paresthesia is a medical term used to denote these sensations, which are sometimes commonly described as a "pins and needles" feeling.[] Mild recovery Disputed Neurogenic Thoracic outlet syndromes with no objective plexus change Rib changes: None Symptoms: Variable; Few objective Pain & paresthesias: lower[]

  • Peripheral Neuropathy

    Chemotherapy-induced peripheral neuropathy is a debilitating side effect of chemotherapy, which manifests as paresthesias, dysesthesias, and numbness in the hands and feet[] […] and weakness of the thenar muscle group.[] Patients present with pain, paresthesias, or weakness along a specific nerve distribution or experience generalized peripheral neuropathy.[]

  • Entrapment Neuropathy

    During this process, typical symptoms of neuronal injury arise, such as pain, paresthesia, and numbness.[] In advanced cases there may be atrophy of the thenar muscles, especially in the abductor pollicis brevis.[] Neuromuscular examination revealed severe atrophy in the thenar, hypothenar, and interossei muscles on the right side, as well as moderate atrophy in the left interossei and[]

  • Cervical Nerve Root Avulsion

    The symptoms only occur on one side and may include weakness and paresthesia (numbness or tingling) in the involved extremity for several seconds to several minutes.[] Sensory disturbances such as coldness, numbness, and tingling also occur and are associated with impairment of light touch, pain, and thermal sensation.[] Symptoms of this type of injury are known as “stingers” or “burners” since they cause unilateral burning in the affected arm, as well as weakness, paresthesia, and the inability[]
