Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.
Call emergency services for severe breathing difficulty, choking, sudden paralysis, or a major new neurological change.
These symptoms are not typical of every case, but they require immediate assessment.
Emergency care is not usually needed simply because an MRI shows a syrinx without a sudden change in your condition.
If you already have syringomyelia, contact your care team promptly when symptoms are new or clearly worsening.
This includes increasing weakness, more frequent falls, spreading numbness, new swallowing difficulty, or changes in bladder or bowel function.
Seek urgent medical assessment for rapidly worsening weakness, sudden difficulty walking, new loss of bladder or bowel control, or inability to pass urine.
Arrange a routine appointment if you develop ongoing numbness, unusual loss of pain or temperature sensation, unexplained hand weakness, muscle wasting, stiffness, balance problems, or headaches triggered by coughing or straining.
Routine follow-up remains important when symptoms are stable.
Every sign above is quoted from the sofidex article on Syringomyelia. If you are not sure, err upward — it is always reasonable to be checked.
