Postural imbalances can be caused by numerous things such as sleeping on a bad mattress or sitting for long periods without moving around or proper stretching. When muscles pull out of range they can cause strain on neighboring or antagonistic muscle groups
The longer they pull on each other the greater the dysfunction. I work with acute or chronic pain caused by muscle imbalances. I do not manipulate joints or bones, I will refer you to a collaborating Chiropractor for that. But I will create space within muscle compartments so that you can function without pain.
