Herniated c5-6 four years ago. MRI showing some spurring as well. Been through the gamut of conservative approaches (PT, traction, Trigger points, TENS, dry needling, ESI, laser therapy, massage, etc.) Still experiencing constant pain almost exclusively in my left shoulder (2/10 on most days; can get at bad as 4-5/10 on other days) Wondering if wearing a cervical collar when I sleep at night would have positive, long term effects on my pain. Opinion? Also very tempted to try flexion-traction from a chiro.
