Sciatica is a symptom of a more serious health problem. The discomfort usually goes away on its own, but if it doesn’t, it’s time to see a doctor or chiropractor in Seneca. If you have sciatica, the first thing your doctor will do is take your medical history and perform a physical exam. This is to determine the cause of your sciatica and rule out other possible causes, such as a tumor or an infection in the spine.
