Although I cross my legs all the time, I work out regularly, etc. but whenever I sit on my knees or cross my legs it gets sore within a minute, especially knees (ouchy!). Now, I don t have insurance so I can t se a doctor about this, I ve always seemed to have joint issues but about a year or so ago I got in a pretty bad skate boarding accident and the worst road burn the doctor had ever seen plus flesh torn off on both knees and both elbows. But on my left knee I had extra fluids in there and the doctor said to come back in in 2 weeks to see if he needed to surgically remove the fluid but I never went back. I still have problems with pain with it today but could that even be because of fluid or because it s just damaged in general? I appreciate all the help. :) Thanks, Doc!
