I tried to ignore it and get ready for work, but it was getting worse by the minute. Finally, I decided to go to the doctor and get it checked out. The doctor told me that I had causalgia caused by a minor injury to my back a few days ago. He prescribed some medication and advised me to rest and avoid any heavy lifting or bending for a few days.
