I may be totally confused on your ? so bare with me. My pain has worsened over time. I have not had this issue well dx anyway for 2 years. I will say when I talked to my doc about things getting worse and this may be wrong but said sometimes things get bad then to see bigger improvement. Also I read that when nerves are regenerating its more painful along when muscles lengthen. Now for meds wouldn't it be better a gradual decrease to see? As for tests isn't there just maybe 1 or 2 you could repeat to see progression? Like the emg possibly? Feel better
