SLD?? REVISION???
Hi Sue ... sorry I can't help you ... and 50 pounds in a year does seem like a bit. Have you noticed anything different (like not getting full no matter how much you eat)? What's your diet like? Are you exercising? I had a 20 pound gain in a 10 month period ... but I've come to the conclusion it was mostly carbs and little protein, and no exercise.
By the way, what is SLD?
I do have BC/BS of IL PPO, but I have no clue if they'd pay for the revision ... I would think they would if its medically necessary, but who knows with insurance these days? I would definitely contact the doc, and then maybe go for a second opinion.
Wish I could help you more! Good luck ... and please keep us posted ... many can benefit from your experience.
