I got into an accident about a 13 months ago. I have had sciatica ever since according to the many doctors I have been to. The pain has been constant and has continue to spread. It is currently affecting me from the top of my back down the back of both legs and now it is spreading to the front of my legs and affecting my knees also. I have not found any relief and swell up all the time. I am 19 years old going through this. I just went to the ER and the doctor referred me to an arthritis doctor because he doesn't think it is sciatica. I'm not quite sure what this could possibly be!
