  14. Nausea: Feeling queasy or vomiting.
  15. Diarrhea: Loose bowel movements may occur.
  16. Malaise: A general feeling of being unwell.
  17. Photophobia: Increased sensitivity to light.
  18. Redness of Mucous Membranes: Eyes, mouth, and genitals may become red.
  19. Hoarseness: Changes in voice quality.
  20. Skin Peeling: Skin may peel after the rash resolves.

Common Diagnostic Tests for Erythema Multiforme Major:

  1. Physical Examination: A doctor examines the skin and reviews medical history.
  2. Skin Biopsy: A small skin sample is taken and analyzed in a laboratory.
  3. Blood Tests: These can detect infections or underlying conditions.
  4. Viral Cultures: To identify specific viruses like herpes.
  5. Chest X-ray: To check for lung involvement in severe cases.
  6. Allergy Testing: To identify potential allergens.
  7. Tzanck Smear: A microscopic examination of skin cells.
  8. Complete Blood Count (CBC): To assess white blood cell counts.
  9. Erythrocyte Sedimentation Rate (ESR): To measure inflammation.
  10. Immunological Tests: To check for autoimmune disorders.
  11. Skin Patch Testing: To identify potential allergens causing contact dermatitis.
  12. Viral PCR Tests: Polymerase chain reaction tests to identify viral DNA.
  13. Throat Swab: To detect streptococcal infections.
  14. Skin Scraping: To rule out fungal infections.
  15. Electromyography (EMG): To evaluate muscle function in severe cases.
  16. Urinalysis: To check for kidney involvement.
  17. Lumbar Puncture: In rare cases, to rule out central nervous system involvement.
  18. Electrocardiogram (ECG or EKG): To assess heart function.
