Your symptoms could be caused by several conditions, including but not limited to pulmonary embolism, even if your potassium and electrolytes are normal.

🩺 Possible Causes

• Pulmonary embolism (PE) can cause chest pain, palpitations, confusion, and fatigue due to impaired lung blood flow and oxygenation.
• Other causes might include cardiac issues, neurological conditions, or electrolyte imbalances not detected by routine tests.
• Muscle cramps and fatigue can also arise from dehydration, medication side effects, or nerve-related problems.

⚠️ When to Seek Immediate Care

• Sudden chest pain or worsening shortness of breath
• Severe palpitations or fainting
• Confusion that worsens or does not improve

🩺 Recommended Next Steps

• Urgently consult a pulmonologist or cardiologist for evaluation, including imaging like a CT pulmonary angiogram if PE is suspected.
• Further blood tests and cardiac monitoring may be needed to identify other causes.
• Avoid self-medicating and seek emergency care if symptoms escalate.
