There are some gentle yoga nd tai chi movements which help when mine acts up, plus the pillow between the knees at night, to keep things in alignment.I was on the regimen of muscle relaxants and anti-inflammatories for over 15 years, off and on, when I finally got fed up, started gentle exercises, watched the posture etc. as Spaw said, and used topical treatments such as Arnica and Tiger Balm.
I would not recommend a chiro. An osteopath is an MD, plus knows manipulation, so it seems a lot safer and I prefer their type of manipulation, BUT a good massage therapist can do WONDERS over them all and a good chiro or osteo will send you for masage therapy, too.
Hope it is getting better.:-)
