Does anyone else get this swollen tightness in their hands and legs when pain is at its worst. I feel totally run down and flu like atm but not flu just the feeling off and got freezing cold waiting for the train to work which makes my pain double. Is the swelling or tightness possibly part of fibromyalgia does anyone know? Thanks all. Feel like I could sleep for 24 hours today after just an hr max a night for days.
