It’s got a warm and fuzzy name, but an MS Hug ain’t the cuddly kind. It’s a band of tight pain around your torso that can range from dull and achy to sharp and burning. The pain can sometimes make it hard to breathe, giving it the nickname "MS girdle."
The MS hug happens when messages from nerves are blocked or disrupted by the damage caused by MS. The feeling of tightness can be due to spasms in the small muscles between your ribs which help expand your chest when breathing.
