I believe I had this symptom, the MS Hug, ~ 10 years before I was diagnosed with MS. I had overindulged in chocolate...then had ~ 4 days of the MS Hug. Doctor thought it was liklely a gall-bladder attack, and told me to avoid fatty foods. That i did, and never had that symptom again. No symptoms untiI 10 years later. Lotsa relapses now though.
