Hi,
While not disagreeing with what has been said, you should not rule out the possibility of CRPS. Regardless, given the deconditioning post injury, any rehab must be respectful of pain limits, as pushing too hard will exacerbate the problem particularly if CRPS is the predominant pathology. Certainly, your presentation is a little different to what would be expected from a simple strain, and any soft tissue damage should have shown up on MR. CT is a little more sensitive for identifying occult bony injuries however.
Regardless, your prognosis is good assuming no unidentified bony injury as long as you rehab appropriately.
Good luck, Matt
