<s>[INST] My mom has Brown sequard syndrome and has been stable on several nerve and pain mess for years. Tonite she is having some mild abdominal fullness, muscle cramping/spasms in legs and neck, and slightly nauseated. No new mess on board. Any ideas? Been eating and drinking fine. Just came on this evening. [/INST] Hello!Welcome on Healthcaremagic!You should know that Brown sequard Syndrome is a damage of the spinal column. It can not cause such symptoms, as it is a past lesion. For this reason, I recommend bringing your mother to the ER and having some tests to investigate for the possible causes of her symptoms: - an abdominal ultrasound- blood electrolytes for possible imbalance- complete blood count, PCR, ESR for inflammation. Hope you will find this answer helpful!Best wishes, Dr. Aida </s>
