Yes, but I know I had a concussion event at age 15 , and my shoulders, hips even eyes & ears have been slightly off level for quite awhile.
So it made sense to me after I found out about upper cervical..

Plus the chiro was a multi modality practitioner, so soft tissue /posture was addressed also.

If anyone has had any head/shoulder hits or falls , sport injury, it might be a good thing to look into..
Many w/TOS do report uneven shoulders..and later on hip problems...

Some upper cervical hard liners will say it will fix everything.. but I and many others on the PCS/TBI forum don't agree with that, we feel many other therapies are valid and a mix is needed for each individual..
