Chiropractic involves spinal manipulation to treat a wide range of conditions. Chiropractors believe that disease is caused by pinched nerves in the spine.

Manipulating or adjusting the spine is thought to remove the pinched nerves, or subluxations, which will allow the body to heal. Chiropractic was developed in 1895 and has grown to be one of the most popular alternative therapies. Many believe it's so popular that it shouldn't be called "alternative" medicine.

People commonly use chiropractic manipulation for back pain, neck pain, and headache. It is also used for joint pain, migraine, high blood pressure, scoliosis, anxiety, and many other conditions, but there is no good scientific evidence to support most of these other uses.
Chiropractic procedures are likely safe for most people when done correctly. However, procedures on the neck can cause side effects including headache, neck pain, and neck stiffness. Some side effects have been severe, such as stroke and bleeding around the spine. But this seems to be very rare.

Special Precautions & Warnings:

Pregnancy: Chiropractic procedures are possibly safe when used during pregnancy for up to 10 weeks.

Breast-feeding: There isn't enough reliable information to know if chiropractic procedures are safe when breast-feeding. Stay on the safe side and avoid use.

Children: Chiropractic procedures are possibly safe in children when done correctly, short term. Serious side effects are rare, but some cases of bleeding in the brain have been reported in children.

Cancer: People with certain cancers that reduce bone density or bone strength might have an increased risk of bone fractures during treatment.
