Who has pain really bad down your spine ? It feels like someone has their hand around my spine and squeezes really hard ,lets go and then does it again. I have a terrible time every morning with this .I have really good mattresses and have just in the last couple weeks had this get really bad. Also my arms and legs feel like there is pressure up and down them. Is this another degree of FM or does it sound like something else ? I guess I'm still trying to figure out what is FM/CFS and what could be caused from something else.
