Fibromyalgia: a chronic disorder characterized by widespread pain, tenderness, and stiffness of muscles and associated connective tissue structures that is typically accompanied by fatigue, headache, and sleep disturbances

Allodynia: pain resulting from a stimulus (as a light touch of the skin) which would not normally provoke pain.

My wife has fibromyalgia.  Sometimes, her pain sensitivity approaches allodynia levels.

I took her a glass of soda today, and my arm brushed hers.  She recoiled in pain and snapped at me.  Evidently, my touch shocked her.

I didn’t even feel it.

It’s very hard not to feel guilty or take it personally.
