Non-surgical treatments include bracing, oral non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin, and intracarpal tunnel injections of corticosteroids (e.g., prednisolone acetate); surgery is considered if conservative treatment options fail.
(2) Poorly controlled diabetes causes peripheral neuropathy, which can lead to numbness in the fingers. Commonly used drugs include tricyclic antidepressants such as amitriptyline, anticonvulsants such as gabapentin, and nutritive nerve drugs such as cytidine diphosphate, along with hypoglycemic drugs such as sulfonylureas and biguanides.
