<s>[INST] I am 40, 5ft 7, 280lbs when I was 24 I started getting muscle cramps throughout my upper body, around my ribs. They became more severe as I got older. I have been on baclofen and oxcarbezepine. I was first told I had Dystonia, and now Stiff Persons Syndrome. The muscle cramps slowly started effecting different areas. My arms, neck, tongue, feet, but mainly severe in my trunk area. It seems to be worse when it is cold outside. Getting the shivers from being cold can set off multiple cramps throughout my body in a way that almost locks my body down. Not sure how to explain that, I just freeze up from the cramps. I want to know if this could be something else, rather than Stiff Person syndrome. Is there a better medicine that could help? I also now have flinching throughout my body on a daily basis. There is nobody that I know that I can ask or compare symptoms with SPS to see if that is actually what I have. [/INST] Hi, First of all your symptoms are not Stiff person syn Chat Doctor.  If you take baclofen and other muscle relaxants obviously you will have dystonia.  Your symptoms are quite different, But we follow a distinct protocol: 1. To check your electrolyte imbalance-You can take supplements or ORS solution2. Next if its not working go for some basics stretching of your limbs3. Still, if you feel it's not reliving better go for an NCV Nerve conduction velocity test. Hope I have answered your query. Let me know if I can assist you further.
