Hi, I found out last October that I have arthritis in both of my knees, I m female and overweight, but I have lost 50 pounds since I found about my condition, but now my pain is severe and it s hard for me to walk sometimes without feeling like I m going to fall, it feels like my knee is slipping out of joint and then goes back in and it causes extreme pain, I wanted to go to the emergency room today because I ve been dealing with this for 2 weeks and my pain medicine isn t taking away the pain anymore and my job requires a lot of walking and up and down from sitting at a desk, so my question is should I go to the emergency room
