Hi,i didnt even know what crps was until 2 months ago. I have it in my face,the right side,which includes side of head,but can include all of my jaw,and sometimes one side.My collar bone was also affected.My pain travels.Weirdy,i have had 'back ache' up the top left side,so am not sure if that would be a separate issue.Thats been consistent for 3 weeks or thereabouts. I will look at the link. Thanks. Barbara
