Treating a torn ligament?

So I just found out that an ankle "sprain" I got about two months ago is actually one torn tibiafibular ligament, one partially torn talofibular ligament, and bruising on the bone throughout the ankle. I'm on Tricare and I don't see an orthopedic specialist until the 7th of June. Anyways, after seeing everything in writing from my doctor, I'm kind of freaking out. The pain has been stellar, but I have been walking (limping) without crutches for a little over a month now. Is it possible that I might still need surgery? If you've ever had this type of injury, what did you do for treatment?
