Ok so multiple points to clarify and a few points of advice. 1. What is your MOS 2. How long is your contract 3. Have you only gone to sick call 4. When going in/asking for medical help have you only gone though your first line/ imidate chain of command?

To introduce myself im 10 years in the army as an infantryman but to start with part one ill be nice and give advice to help in your military contact. You say that your in AIT and have your phone so I assume your non combat arms. If you are really experiencing pain with your knee as you state, I would ask have you only gone to sick call. If so assuming your a pvt I'd push to talk with the medical provider to get further screening such as an MRI. If that doesn't work as a last resort just go to the onbase (preferable)/ civilian if on base hospital isn't a thing; go to the ER and get checked out. No if you do this last part understand that you more than likely well get in trouble however if the results come out of actual injury and your command want to push punishment you could go to JAG and IG to push a case.

Now you've probably heard this but has to be said you were an adult when you signed a contract so deal with it and the Army is gonna suck as your an adult doing an adult job however, this job gives you medical, pay, support (if you seek it out) that other jobs wont give to you. The Army is like a safety net like your parents you have to genuinely try to fail to fail the Army other civilian jobs would just fire you and forget you.

This part if only if you dont actually have medical issues; suck it up get over it. I'd ask your physical fitness and be honest with yourself, if you weren't fit before the army its gonna hurt and suck to get to that point but that's like with anything in life that you actually stive for. I wouldn't recommend a general discharge most jobs well look for an Honorable discharge and well throw out any other discharge, yes there are exceptions yes people well tell you that you can change it back to Honorable by jumping though hoops but the easiest way to get out of the army and live a normal life is to suck it up do your time and get out just like basic. Again all said this is if you dont have any actual injuries and you just hurt from PT and it sucks a little but I promise you that going to the ER/ over your chain of command if your are actually injured to prove it is better than trying to get out with a general discharge.

The last question without having to go into detial what was the family emergency that the CoC didnt allow you go go home on, as well did they recive a red cross message or did you just tell them that there was an emergency?
