How can suboxone make my legs swell to enormous unbearable sizes?

Side effect?: I have seen this a few times with a few folks who seem to have an allergy of sorts to the Naloxone component of the suboxone. I suggest you start by discussing this matter with you dr. With my patients, sometimes it helps to not swallow the juices after the Suboxone dissolves by spitting it out. If that doesn't help, you may need your dr to switch to subutex which doesn't contain the naloxone.

Suboxone: This can be seen in patients allergic to naloxone, which is a component of suboxone. Consult your doctor for alternative tx.

It doesn't: It is extremely unlikely that Suboxone is the cause of your leg swelling. If narcotics or other opiates didn't do this to you then Suboxone certainly didn't do it , either. Therefore i recommend you be evaluated by a physician to find another possible cause for your swelling. I bet it turns out to be something else.
