Side effects after neck manipulation occur in one out of every three patients. That's about 30 percent of the people getting this type of treatment. Usually the symptoms go away after a few hours up to a day. Patients report dizziness, ear symptoms, or headaches. Other side effects can include increased neck pain or numbness and tingling down the arm. Some patients get pain in a new location like the back or chest.

Call your doctor and report your reaction. Make a follow-up appointment or get a medical opinion from another doctor if the symptoms don't go away.
