sacroilliac joint

Hi there, I have been suffering from chronic lower back pain for 2 years now. My Osteopth has advised I have an sacro illiac issue. Whilst I has been improving slightly it is not getting better and I’m getting so frustrated because this injury seems to be going on for ever. I have a lot of pain and cluncking around the lower back and I’ve had terrible trouble with my left leg. Muscle tightness etc. Now it’s shifting over to my right side. Do you think a chiropractor would be able to help this problem? Kind regards,Michelle c
