That sucks. If it is a serious problem, are you sure you want to take the risk of joining the army and then have something bad happen? Hopefully you will be able to get a waiver and join. I'm an E-4 in the Navy, but I'm planning on joining the army soon. I'm in Iraq right now with a CA Brigade and I kind of like the army alot more than the Navy. Hopefully everythin will work out for you.
