Anxiety or Panic Disorder: This condition is characterized by recurrent, unexpected panic attacks that can include symptoms such as chest pain, palpitations, and a feeling of impending doom or death. The electric shock pains could be related to the intense anxiety causing muscle tension.

Costochondritis: Inflammation of the cartilage that connects the ribs to the breastbone can cause sharp chest pains, which might be perceived as electric shock-like. This condition is relatively common and can be exacerbated by movement or deep breathing.
Musculoskeletal Issues: Strains or injuries to the muscles or tendons in the chest wall can cause intermittent pains that might feel like electric shocks, especially if the pain is related to movement or position.
Gastroesophageal Reflux Disease (GERD): GERD can cause chest pain that might be intermittent and could potentially be described as feeling like electric shocks, especially if the pain is related to eating or lying down.

Acute Coronary Syndrome (ACS): Although less common in a 26-year-old, it's crucial not to miss ACS, which includes conditions such as myocardial infarction (heart attack). Chest pain is a key symptom, and while the electric shock description is unusual, the potential consequences of missing ACS are severe.
Pulmonary Embolism (PE): A blood clot in the lungs can cause sudden, severe chest pain and is a medical emergency. The description of electric shock pains is not typical, but given the potential lethality of PE, it must be considered.
Cardiac Arrhythmias: Certain arrhythmias, such as supraventricular tachycardia (SVT), can cause chest pain or discomfort and might be perceived as electric shock-like sensations due to the abnormal heart rhythms.

Neuromuscular Disorders: Conditions like multiple sclerosis or peripheral neuropathy can cause a wide range of symptoms, including pains that might be described as electric shock-like. However, these conditions are less likely given the age and presentation.
Mitral Valve Prolapse: A condition where the two valve flaps of the mitral valve do not close smoothly or evenly but instead bulge (prolapse) upward into the left atrium when the heart contracts. It can cause chest pain, palpitations, and might rarely be associated with unusual sensations like electric shocks.
Hypokalemia or Other Electrolyte Imbalances: Severe imbalances in electrolytes like potassium can cause muscle weakness, arrhythmias, and potentially unusual sensations like electric shocks, though this would be less common and typically associated with other significant symptoms.
