Are You Familiar With Chiari Malformation And Syringomyelia? I Got

Are you familiar with chiari malformation and syringomyelia? I got the decompression surgery three years ago and felt good for a year and a half but then symptoms came back. Got an MRI and the doctors said the syrinxes look the same so they said I was fine. But what about the symptoms coming back? Have went to lots of different doctors but they say they don't see a problem because the MRIs look good. Have been put on different medicines but none really working. Are there any medicines that help with symptoms of chiari and syringomyelia?
