Methylcobalamin capsules do not treat head neuralgia, it is mainly used to treat peripheral neuropathy.

For diabetic peripheral neuropathy caused by numbness at the ends of the limbs, lumbar spondylosis compression caused by lower limb numbness have a better effect, but for the head neuralgia effect is not obvious. Head neuralgia mainly refers to migraine, tension headache, cluster headache, the treatment of drugs can choose ibuprofen, indomethacin and other anti-inflammatory analgesics, or pregabalin, gabapentin and other drugs to control nerve pain. But generally do not choose methylcobalamin capsules for treatment.
