Well that's confusing

So I'm on my second physical therapy appointment. They are going well so far - a few exercises for me to do, but the best is this treatment called ionotophoresis (I think that's how you spell it, but then again I'm not an MD). It is basically where they hook you up to what looks like a car's jumper cables to more effectively deliver medicine to the affected area. This works well for me since, given my Crohn's, anti-inflammatories and I don't get along very well. It feels really weird since they can amp up the juice on it and you start to feel little tingles where it's connected. Here's a picture of it (no comments about my bird legs):

But here's the confusing part - everyone treating me seems to have differing opinions on what the hell is wrong with me. The orthopedist says yes, I definitely have stress fractures on the tops of my tibias. The physical therapist says nah, it's more your bursitis that's bothering you, so those crutches probably aren't as necessary as you think. Then there's the PT Assistant who jumped on me today because I was hobbling around the PT office without my crutches, telling me I shouldn't be putting weight on my knees unless I'm doing the prescribed exercises. Orthopedist says my running days are over; therapist says I'll definitely be able to run again, but it will just be about 6 months before I can even think about starting again.

So what's a girl to do? I'd of course love to believe I'll be able to run again, but somehow I don't think that's probably my best move. Maybe I can pick up cycling after this is all said and done and eventually do some of those long cycling events (Alston, you'll have to give me pointers!). Right now I think I'll just rest the ol' legs as I've been instructed and not make anything worse! Although this whole "rest" thing? WAY overrated.
