For different causes of finger numbness to take different methods of treatment, it is impossible to say exactly which treatment method is best.
If the numbness of the finger disappears completely after removing the cause, no treatment is needed. If the numbness is caused by Raynaud’s phenomenon, the first thing to do is to actively treat the primary cause, and when the symptoms are severe, it is necessary to apply vasodilator drugs. If it is caused by carpal tunnel syndrome, the wrist joint is often placed in a neutral position (neither flexion nor dorsiflexion), and intracarpal tunnel injection of glucocorticoids can achieve good results. If it is caused by cervical spondylosis, good results are obtained by nerve nutrition, muscle relaxation, pain relief and other medications, as well as after traction and immobilization treatment.
