As a physician, i usually start with the most ominous possibilities first, rule them out, and proceed with less worrisome causes. Top of the list is to rule out blood clots. Given the fact that your swelling is in both legs and that the ultrasound was negative (normal), it is safe to say that is not the source. Sometimes those studies will describe valvular insufficiency, a problem with the valves in your veins not working so well. This could benefit from compression
stocking that your doctor could perscribe. There are other ominous causes that your history does not elaborate on. Your doctor probably has evaluated you for congestive heart failure
and kidney problems
. Sometimes thyroid problems can contribute to this as well. If those issues are not the source, a review of your medications may be revealing. Certain meds are notorious for causing this, like Norvasc
. Finally, yes, the narcotics may be contributing, but getting of them at present may be hard. You may be sedentary from your pain and that could contribute as well. Sitting for prolonged periods makes it hard to mobilize the fluid that accumulates in the lower parts of your body. If able, regular activity may help. Ultimately, you may benefit from diuretics, a class of meds that help your kidneys get rid of excess fluid in conjunction with the compression stockings. Good luck!
