Many patients experience unexplained chest pain that has been misdiagnosed. The pain is often caused by a slightly misaligned rib that does not show up on x-rays. Manipulative therapies like chiropractic adjustments and acupuncture can quickly treat the pain from rib misalignment. A combination of an adjustment popping the rib back into place along with acupuncture to reduce muscle spasms typically relieves the pain within two to three weeks with a low rate of relapse.
