Signs & symptoms

Symptoms of Achenbach syndrome can include:

- Sudden onset of pain in one or more fingers
- Swelling and discoloration of the affected finger(s), typically blue or purple in color
- Tenderness to the touch
- Numbness or tingling in the affected finger(s)


The diagnosis of Achenbach syndrome is typically made based on clinical presentation and ruling out other possible causes of finger pain and discoloration, such as trauma, infection, or circulation problems. Medical imaging such as ultrasound or MRI may also be used to confirm the diagnosis and rule out other conditions.


Treatment for Achenbach syndrome is primarily symptomatic and supportive. This may include applying warm compresses to the affected finger(s) to improve blood flow and alleviate pain and discomfort. Over-the-counter pain medications such as acetaminophen or ibuprofen may also be recommended to relieve pain.
