Nerve block therapy for pain relief usually works at the time of treatment, but complete eradication requires treatment of the cause.
Nerve block can be used for migraine, frozen shoulder, herpes zoster, trigeminal neuralgia and other primary or disease-induced pain. By blocking the nerves that conduct sensation with drugs to achieve the purpose of analgesia, the clinic commonly used drugs such as ropivacaine and triamcinolone acetonide. The pain disappears after the nerve blocking drug is injected.
But this analgesia does not change the condition, if the primary disease such as frozen shoulder, herpes zoster and so on continue to deteriorate, the effect of this analgesia is short-lived, so it is also necessary to treat the primary disease. For example, for herpes zoster, antiviral drugs such as valaciclovir and famciclovir can be used, nutritive drugs such as methylcobalamin, and anti-infective drugs such as topical acyclovir cream and neomycin ointment can be used.
The above drugs need to be used under the guidance of clinicians, unauthorized use of drugs is prohibited; whether to carry out nerve block, how to carry out, it is recommended to have a clinician according to the condition.
