Hi Itzagi,
Have they tried you on Topiramate? I take it for my Chronic Cluster Headaches, and really noticed in February this year when I upped the dose, that the side effect that has it reduce Neuropathic Pain - through some magical system - cuts my TN pain, and the pain from the Paresthesia, by a couple of points. Add Lidocaine Infusions and Oral Ketamine to this mix and the TN pain goes from 15 to 7-8 on a scale of 0-10, and the Paresthesia is a 4.
If only the Topiramate worked as well on the Cluster intensity. Ho-hum
Dave.
