I am glad to hear that you get in the pool some. How often do you go? Can you walk pain-free in the water (even if you have to weigh next to nothing by standing up to your chest or more)?
I obviously can't give any medical advise but I can tell you what worked for me. I had heard of incredible recoveries by people that worked out 4 hours (or more) in the pool a day...even some that were told they would never walk again. It made sense to me because in the water I become virtually weightless and all my bones, ligaments and joints are floating without the stress that gravity normally brings. I could do all the exercises in the water pain free that caused me enormous discomfort even in bed (one of my legs probably weighs 35 pounds and even sliding it adds even more from friction... and so on). When injured gravity is not my friend! But in the water movement ranges from effortless to as much resistance as you want to create (by just moving faster and faster in the water).
I just started walking forward, backward and sideways at the beginning in the depth of water I found that removed all the pain (above my belly-button). Soon I was running in all directions, doing jumping jacks, cross-country skiing, treading water at the same depth... then after a few days I could do it in progressively less and less water depth (so I was able to put more and more weight on it pain free).
Today only 4 months after my surgery I am playing tennis almost every day (some light doubles but mostly just rallying back and forth right to each other....which is what I really love doing anyway

I am 60 years old and put the surgery off for 6 years (not being able to play at all and with a horrible limp).
Before I started using the pool I could not stand on just my new hip for even 1 second without intense pain and feeling like it would collapse. Now, after 2 months in the pool (5 times a week for 1 or sometimes 2 hours) I can stand on just my new leg all by itself while I do lifts and swing the other leg around without any pain!
Someone told me that exercising in water not only builds my muscles and connective tissues from the resistance but that the increased circulation that comes from the aerobic movement does perhaps even more good by delivering "rush order" all the building blocks needed to heal or grow strong.
When I was 13 I learned how important circulation is. I had an allergic reaction to a medication and had to be rushed to the ER I was itching so bad I wanted to tear my skin off. There they gave me a shot of something and within 15 seconds or so I felt normal again. I exclaimed WOW what was that?? They told me adrenalin... and that all it did was just make my heart pump faster so my organs could clean my blood. Yes, circulation makes that much difference! Remember...kids don't try this at home without consulting your doctor... yada yada .... Glad to hear you're getting 2nd opinions!
Btw, at home I tried to be flexing my leg, "squeezing my buns together" and pumping my ankles all day long even while just sitting watching tv. ....adds more circulation too!
