Differential Diagnosis for Increased Skin Sensitivity over Back and Flanks
- Single most likely diagnosis
- Shingles (Herpes Zoster): This condition often presents with increased skin sensitivity, pain, or burning sensation over a specific dermatome, which can include the back and flanks. The rash typically follows the distribution of the affected nerve.
- Other Likely diagnoses
- Contact Dermatitis: Irritation or allergic reactions to substances like soaps, detergents, or plants can cause skin sensitivity and rashes on the back and flanks.
- Eczema (Atopic Dermatitis): Characterized by itchy, inflamed skin, eczema can occur anywhere on the body, including the back and flanks, and may cause increased skin sensitivity.
- Insect Bites or Stings: Reactions to insect bites or stings can lead to localized skin sensitivity, redness, and swelling.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Multiple Myeloma: Although rare, multiple myeloma can cause skin sensitivity due to amyloid deposits or nerve damage. Early detection is crucial for effective treatment.
- Sickle Cell Disease: In rare cases, sickle cell disease can cause skin sensitivity and pain due to vaso-occlusive crises affecting the skin.
- Lyme Disease: If left untreated, Lyme disease can lead to neurological and skin manifestations, including sensitivity and rashes.
- Rare diagnoses
- Sjögren's Syndrome: An autoimmune disorder that can cause skin sensitivity, dryness, and rashes, although it is more commonly associated with dry eyes and mouth.
- Mastocytosis: A condition characterized by an accumulation of mast cells in the skin, which can cause skin sensitivity, itching, and flushing.
- Neurological disorders (e.g., neuropathy, radiculopathy): Certain neurological conditions can cause skin sensitivity due to nerve damage or dysfunction.
