Nonthermal blisters of the ankle are caused by a variety of conditions, including inflammatory disease, infection, trauma, and vascular disorders.
Diagnosis of nonthermal blisters is based on physical examination and medical history. A skin biopsy may be required to confirm the diagnosis.
Differential diagnosis includes contact dermatitis, insect bites, shingles, and drug reactions.
Treatment for nonthermal blisters of the ankle depends on the underlying cause. In some cases, medications may be prescribed to reduce inflammation or infection. In more severe cases, surgery may be required to repair damaged tissue.
The prognosis for nonthermal blisters of the ankle depends on the underlying cause. If the condition is treated promptly and appropriately, the prognosis is usually good. However, if the underlying cause is not addressed, the blisters may recur.
