TMJ - Botox relief

Hi there, I have suffered from TMJ for approx 7 years & also have Arthritis on the left side of my jaw due to this. I take 4 tramadol & 3 Diclofenac each day to try and help the pain. I went to see a surgeon 2 weeks ago as they were going to try & 'wash' out the joint to see if that would help. When I got to the hospital they explained that, as a last ditch attempt before the surgery they wanted to try botox. So I went back 4 days later & got 8 injections of botox on both sides of my face (so 18 in all) into my jaw muscles. It wasn't too sore on the right side, but the left side was fairly painful!! lol However I have seen an improvement in the pain already! I was just wondering if anybody else here has had this treatment & what they have made of it? This is the 1st time I have been here, so I apologise if there is a post elsewhere about this! x
