My husband has Trigeminal Neuralgia on his lower lip. When it flares the pain is around his lower left lip and radiates on the left side of his face. The pain is very intense! Poor guy... I feel so sorry for anyone who suffers with this pain. I've had Shingles (twice) this year on the back of my head. So I think I understand a little. My question is... my doctor gave me some Lidocaine Patches 5% to treat my nerve pain from the Shingles. My husbands TN flared up yesterday and today is bad. The medication he takes for this is CarBamazepine ER 100mg 1 or 2 Daily. He took 2 yesterday and his pain was much worse this morning. This Medication really affects his memory and functioning. I was wondering if I could cut a small section from a Lidocaine Patch and put on the area on his chin (under his lip) where the nerve pain seems to start? Has anyone tried the Lidocaine Patches for Nerve Pain on the face? If so, did it help? I have searched and searched, but can't find any information if you can use these patches on the face or not. If anyone knows anything about this I would Greatly appreciate your reply. Thank You!
