i recently got my ratings from my dislocated knee surgery repair and received 10%. however, due to this being a lifelong issue, additional problems in my knees, not being able to claim both knees (same incident just a difference in severity however there's still damage) and more serious than it appears on paper, I believe I deserve medical retirement. I've heard it's difficult to argue and even impossible to change the rating but i was wondering if there was anyone I should contact. during my physicals the only thing they checked was range of motion, my interview was done over the phone, and I didn't get a lawyer because I just wanted the process to be done with. i know i made a mistake with not negotiating first but now I'm not sure what to do or who to contact. I'm still in the army and I've heard it's better to argue once discharged but i just wanted to know if there's anything i should do before I'm officially a civilian again. thank you.
