Hi, My mum suffers from trigeminal neuralgia and 2 days ago had the microvascular decompression operation. They found an artery irritating the nerve and so moved it. When she woke up, she was suffering the same, if not worse trigeminal neuralgia pain than before. Is this normal or does it mean the operation hasnt worked? So many people from what I ve read, say they wake up pain free and have just the pain from the operation.
