Welcome to HealthcareMagic forum.
It seems like the legs are more troubling than the broken arm.
It's not very clear if the problem is located to one limb or both the limbs
. If the cause is unilateral perhaps vascular causes needs to be ruled out by a color Doppler scans. Bilateral swelling are most likely associated with systemic medical illness - renal system in particular.
I am not very sure if it is a good idea to wait till Sept 14th.
If I were to be your treating doctor, I would perform the initial evaluation like renal function test, hemogram along with Doppler study while continuing on frusemide. I also hope you are keeping your limbs elevated and cellulitis
is been ruled out completely.
Hope this helps.
I wish you a speedy recovery
