Everyone gets an itch on their nose but to have an itch that never goes away, and on a nose that is completely numb, is aggravating. I have been told this is a symptom of MS and the sensation of itching is a phantom one. I can stop the itch by touching my nose [I don't feel it, though]. I think this short circuits the brain. Unless there's something that can be done, you'll always spot me in a crowd with my finger stuck to my nose. Any suggestions?
Neurogenic itching is, well, annoying as you’ve learned. I would suggest that your doctor give you a trial of the the usual remedies first; this includes gabapentin, pregabaline, and carbamezpine in that order. If this doesn’t work your doctor should try a low dose tricyclic next such as nortriptyline. If this doesn’t work a trial of 8% intranasal lidocaine spray should help determine if a selective percutaneous Radio-Frequency rhizotomy of the Gasserian ganglion will work.
