I wish I could loan you the infared jade disc mat, because it helped me get over the agonizing back pain I was in after being positioned oddly during my colonoscopy. I could not walk and I was terrified that my husband would not be sympathetic to something new to deal with.
Regarding work, I know how you feel, but please be careful not to push yourself to the point of no return. I did that, got much worse and lost my job.
My daughter highly recommends this which eliminated her shoulder and back pain in two sessions.
