Painful symptoms may still occur after shingles has crusted over, as treatment for shingles has removed the virus from the patient’s body but has not fully repaired the nerves damaged by the virus. In addition to pain, patients may also feel recurrent itching of the skin. In this case, the patient does not need to use antiviral drugs, but needs to take oral pain medication, such as ibuprofen, and drugs to promote nerve repair, such as vitamin B12. Physical therapy can also be used to promote nerve repair and relieve itching and pain as soon as possible.
