Woah. I do actually remember you mentioning this last year. Is there anything you can do yourself to help it or is it literally just a "wait and see" situation?
I've been lazy about it because I'm so busy with school and kid but I can walk/bike to build up strength and endurance. Running isn't really an option, if I get too out of breath I get oxygen deprivation to my limbs and I fall down and break my ribs.
You weren't here but a few months back I tried to run sprints with my son. My legs gave out and I fell and broke three ribs. All good now though.
