A long time ago, after finishing a marathon, my ankle swelled up. Turns out I had a fracture, I was wondering why it hurt so much during the last part of the run. I never stopped diving, but it hurt. My tolerance for pain is high.
However, now 3.5 years ago, I fractured my femur in multiple places, shattered it. That hurt and redefined my pain scale. I did not dive for nine months and really it took nearly a year. I started cycling on an indoor trainer at two months and went back to my regular swim schedule. I still cannot run unless I am on the padded track at the Y. The biggest issue keeping me from diving was atrophy of the leg muscles and the inability to walk with a tank on. So beach dives were out, on boats, I had to sit down and scoot along on my rear to the stern or if possible, just roll over the side.
In any case, if you can walk without pain then you can probably use your fins. If possible you might do some pool swimming with fins, maybe start with some small "swimmers" type training fins and then move up to your SCUBA fins. So really you can answer your own question, does it hurt when you use fins and can you tolerate the pain if it does?
