HI, im new here so sorry if this is wrong or in the wrong spot.
On September 27,2011 I played a game of football and ended up in tears after the game because of my knee. I iced it and compressed when i went to school. When i got home it was super swollen so i made an appointment with my orthopedic dr. He had 3 ideas but told me to wait and see. SO i waited and in the end he said it was a small meniscus tear and that i have a MCL sprain and sent me for physical therapy and put me in a brace. After 3 months of pt and nothing helped, finally my surgeon decided since he was switching hospital groups that he would do it. I had surgery on January 5, 2012. Surgeon came out to my mom and told her that they were wrong it was a huge meniscus tear  that was irritating the MCL therefore the MCL pain too. I had a repair and was order nonweightbearing for a week and a half and the regular physical therapy. Around 3months post op i ended up spraining my MCL again and had to hold off of pt. Then i got back to pt...Anyways after i finished pt i was released and set for sports again. Mid June I had a dog in my hands and their was an inflatable tube in my way so i kicked the tube out of my way. But i felt something catch. I had to straighten my knee because i was mid step but it was excruciating. I went to the surgeon and he said that it was scar tissue that caught and dismissed me once again. Then this August i was working out and i felt pain but blew it off as the ache muscle feeling when you workout and i babied it just in case. I went shopping a week later and I couldn't even walk because my knee hurt soo bad and i was only shopping for 20mins(flat surfaced no stairs). I waited 2 weeks and it didnt get better and went to the surgeon again and he did another MRI and said "you knee is perfect, i wish i had your knee, you fine" when i asked what should i do with the pain he said "just deal with it and i guess take pain relievers as needed". Now its Oct 2012 and im still having pain. When i fully straighten my knee it hurts really bad and i feel like theirs something in my knee preventing me from bending different ways. At times i cant even move my leg an inch because it hurts so bad. Now my question is what do i do? I dont want to go back to my original surgeon and get blown off again like all the other times. Ive been telling my mom about my pain but shes blowing me off saying its scar tissue and i should just do deep tissue massages to help. I honestly never believed that it was scar tissue in the first place and ive been wearing the brace too. Im in life-guarding for gym and sometimes it hurts to even swim because of the treading and kicking water. DO you think its the meniscus again and my surgeon was wrong? Should i go get a 2nd opinion? Should i try the deep tissue massages even though my pt did it and it never helped me? I need suggestions please. Thank you

Oh. P.S Im 16 female and i am overweight but ive been trying to lose weight but i cant do anything right now because of my knee. And Im from U.S.A
