I have been getting the internal vibrations along with terrible chills, but have no fever. The last time I remember chills this bad is when I was young and had a 104 degree temperature. I am also experiencing sweats along with these also. Gabapentin never worked for me on any of my autoimmune diseases. The only thing they ever gave me doxy. for was herpes virus after contracting it from all places a toilet seat. There are days that feel like every nerve in my body is going crazy.
