<s>[INST] trying to help my 52 year old sister figure out horrible pain that comes and goes on the right side of her neck. Family history older sister passed away after 18 year struggle with MS. Has no insurance as is scared to death it is happening to her too. 3 years age had a eye infection that caused temporary vision loss, which was one of the 1st symptoms of our sister. [/INST] Hello!My name is Dr. Aida and I am glad to attend you on Healthcaremagic!Her symptoms could be related to a pinched nerve in the cervical column or a bulging disc in this level. For this reason, I would recommend performing a cervical spine MRI and a nerve conduction study. It is less likely to be MS, as her symptoms are very localized. Hope you will find this answer helpful!Best wishes! </s>
