A very broad definition of arthritis is swelling in your joints, and in that sense, yes, an accident can cause swelling and pain in your joints. If you are feeling pain from an accident, you should contact a doctor immediately- even if the pain does not seem too bad at first. Do not assume the pain will go away on its own, seek medical help. For help in paying for that medical care, please contact one of our attorneys to help you understand your rights.
