Experiencing convulsions or spasms in the solar plexus area can be unsettling. The solar plexus, located in the upper abdomen just below the sternum (breastbone), is a complex network of nerves and arteries. Sensations of convulsions or spasms in this area can arise from various causes, including:

Muscle Spasms: Involuntary contractions of the abdominal muscles are common and can cause twitching or cramping sensations. Factors contributing to muscle spasms include dehydration, electrolyte imbalances (like low levels of magnesium or potassium), muscle fatigue, and overexertion.
Gastrointestinal Issues: Digestive problems such as indigestion, gas, gastritis, or irritable bowel syndrome (IBS) can cause discomfort or spasms in the upper abdomen. Excess gas or bloating can put pressure on the diaphragm and surrounding muscles, leading to spasmodic sensations.
Diaphragmatic Spasms: The diaphragm, a muscle that plays a vital role in breathing, can experience spasms. Hiccups are a mild form of diaphragmatic spasm, but more severe spasms can cause noticeable convulsions in the upper abdominal area.
Stress and Anxiety: Psychological factors can manifest physically. Stress and anxiety can lead to muscle tension, especially in the abdomen, causing spasms or a fluttering sensation in the solar plexus area.
Nerve Irritation or Damage: The solar plexus contains many nerves. Irritation, compression, or damage to these nerves—possibly from trauma, inflammation, or certain medical conditions—can lead to abnormal sensations like spasms or tingling.
Acid Reflux or Gastroesophageal Reflux Disease (GERD): Acid reflux can cause discomfort in the upper abdomen and chest area. While it's more commonly associated with heartburn, some individuals might experience spasmodic sensations.
Pancreatic or Gallbladder Issues: Conditions like pancreatitis or gallstones can cause pain or spasms in the upper abdomen. These are typically accompanied by other symptoms such as nausea, vomiting, fever, or jaundice.
Abdominal Epilepsy: A very rare form of epilepsy that presents with abdominal symptoms, including pain and convulsions. This condition is more commonly diagnosed in children and is characterized by episodic abdominal symptoms with associated neurological signs.
Aortic Aneurysm: Though less common, an abdominal aortic aneurysm can cause pulsating sensations in the abdomen. This condition is serious and often presents with additional symptoms like severe pain and a noticeable pulsating mass.
What You Should Do:

Monitor Other Symptoms: Pay attention to other accompanying symptoms such as pain intensity, duration of spasms, digestive issues, changes in bowel movements, fever, or any signs of distress.
Consult a Healthcare Professional: It's important to seek medical advice for a proper diagnosis. A doctor can perform a physical examination, review your medical history, and possibly recommend tests like blood work, imaging studies (ultrasound, CT scan), or referrals to specialists.
Manage Lifestyle Factors: Ensure you're staying hydrated, maintaining a balanced diet rich in essential minerals, and managing stress through relaxation techniques like deep breathing, meditation, or gentle exercise.
