It has plateaued but I still have left face pain, burning mouth and left hand/arm burning and stinging (occasionally right hand/arm, too). Pain score of 2-4 out of 10 pretty much every day. Keeping my fingers crossed it doesn’t get worse. It has been almost five years since the onset. I now have episodes where I get sweaty all of sudden but at least it is not painful. The buzzing is almost gone. I never know where and when I will get the symptoms. I hope you are feeling better. Good news is I have not gotten worse. Stay positive!
