Other types of procedures are available to treat specific types of pain, including ketamine infusions, which are to treat various chronic pain syndromes that have a neuropathic component, and botox for chronic migraines.
Injections can help stop migraines before they start. When injected in small doses the Botulinum toxin protein is very good at blocking nerve signals. It can block the nerve signals that can lead to some headaches. During the procedure the doctor will give you series of injections in specific locations in your head and neck. The needle is small and the injections feel like tiny pin pricks.
IV Ketamine infusions are used to treat various chronic pain syndromes that have a neuropathic component. Ketamine produces strong analgesia or numbing in neuropathic pain conditions by inhibition (blocking) of the N-methyl-D-aspartate (NMDA) receptor and by enhancement of descending inhibition and anti-inflammatory effects at central sites.
In clinical settings, ketamine is well tolerated, especially when benzodiazepines are used to modulate the psychotropic side effects. Close monitoring of patients receiving ketamine is necessary and the proposed treatment includes a safe environment with an anesthesia provider monitoring the patient during the infusion.
