Differential Diagnosis for Intermittent Paresthesia in Upper Arms

Single Most Likely Diagnosis

  • Cervical Spondylosis: Given the patient's age (65) and history of chiropractor adjustments, cervical spondylosis is a likely cause of intermittent paresthesia in the upper arms. This condition involves wear and tear on the discs in the neck, which can lead to nerve compression and symptoms like paresthesia.

Other Likely Diagnoses

  • Thoracic Outlet Syndrome (TOS): This condition involves compression of the nerves and/or blood vessels that pass into the thoracic outlet (the space between your collarbone and first rib). It can cause paresthesia in the arms and is plausible given the patient's history of chiropractor adjustments, which might have temporarily alleviated or exacerbated symptoms.
  • Hypertensive Neuropathy: Although less common, long-standing hypertension (HTN) can lead to neuropathic changes, including paresthesia. The patient's history of HTN makes this a consideration, though it's less directly linked to the specific symptom of upper arm paresthesia compared to other options.

Do Not Miss Diagnoses

  • Acute Coronary Syndrome (ACS): Although the patient denies chest pain, ACS can sometimes present atypically, especially in women and older adults, with symptoms such as arm pain or paresthesia without chest discomfort. Given the potential for serious outcomes, it's crucial to consider and rule out ACS.
  • Stroke or Transient Ischemic Attack (TIA): Paresthesia can be a symptom of a stroke or TIA, particularly if it's unilateral and sudden in onset. The absence of other typical stroke symptoms (e.g., facial drooping, speech difficulties) doesn't entirely rule out these conditions, making them important not to miss.

Rare Diagnoses

  • Multiple Sclerosis (MS): MS is an autoimmune disease that affects the brain and spinal cord, leading to a wide range of neurological symptoms, including paresthesia. While it's a less likely cause given the patient's age and presentation, MS can occur at any age and should be considered if other diagnoses are ruled out.
  • Vitamin Deficiency (e.g., Vitamin B12 Deficiency): Certain vitamin deficiencies can cause neuropathic symptoms, including paresthesia. This would be less directly related to the chiropractor adjustments but could be a contributing factor if the patient has a poor diet or malabsorption issues.
