Hi lolak and EnlightenME. If I may join I have some similar symptoms and some accumulated information that might relate.
lolak...Have your neurosurgeons considered repeating the decompression? I understand the procedure when successful usually dissipates the syrinx on it's own once the flow has been properly restored. If not what about the possibility of shunting the syrinx? I had a syringo-subarachnoid shunt inserted in September and most of my symptoms improved immediately...not to say I don't have surgical complications, some of which are severe however it might be an option if your quality of life could improve. And if you don't mind me asking I am intrigued...I have never heard of a burst, could you explain what that is?
EnlightenMe...there has been absolutely no statistical correlation between severity of flow interruption and severity of symptoms so don't feel your small syrinx to be innocent of causing your discomfort, they can cause symptoms at any size. Also, I too have extremity tingling and burning sensations but including numbness. This burning, numbness and tingling is called paresthesia and is often caused when pressure is put upon, or when damage occurs to spinal nerves (called peripheral neuropathy) such as with syringomyelia among other disorders. There are medications that can alleviate some of these symptoms such as tricyclic antidepressants as in amitriptyline and anticonvulsant medications such as neurontin and lyrica. Also the spinal cord houses the nerves that control the diaphragm so paralysis can be a severe symptom of nerve damage...but very rare. I would consult your physician just to be safe, however this is also a very stressful disorder and anxiety often takes the shape of feeling breathlessness.
I hope this helps.:) Meggie
