My case is similar to yours. I developed trigeminal neuralgia after a case of shingles on the scalp and face (including eye) four months ago. I was having agonizing attacks of pain in my eye and scalp until the dr increased the dosage of gabapentin to 1800mg a day. The literature says the pain is the worst pain known to humanity. I concur. When it hit I fell to my knees screaming and crying. It felt like someone was pressing a hot iron against my face and scalp. Though the gabapentin stopped those attacks, the opthalmic part of the trigeminal nerve is still active and it flares several times a day where it feels like it is moving in my scalp. Thankfully these flares are painless. I also have that intense, almost unbearable itching of my lower eyelid and the part between my eyebrow and eyelid is very painful to the touch and sometimes gets red hot. I will look into the things you have mentioned that help you and thank you! I only have the gabapentin and it looks like it may be a long haul.
