@gianni the swelling is such an annoyance when it hangs around. I had quite a bit more with my second hip this summer, too.
I found that doing some manual lymph drainage techniques helped immensely and will leave you some to try, if you are so inclined. I would get myself comfortable and elevated and by the time I did them I would fall fast asleep and wake up with some improvements.
The swelling would return but with regular sessions of it, it kept things moving and it would be less and less over time. The reason this helps is that our lymph doesn't move like our blood does, it doesn't move with the beating of our heart, It needs our muscle's movements and breathing to get it moving and even then it only moves in one direction and that is towards the heart.
Our most powerful uptake areas of lymph fluid is in our abdominal area, hence the deep breathing described below.. I hope this helps.

Take deep breaths.. deep, as in breathing in to a count of 5, or 3 or 4, whatever is best for you. hold it for another count of 5 then blow out completely, still using the count that's comfortable for you. A series of at least 6 of these could help get your excess swelling to move. To ensure you are taking proper deep breaths, place your hand on your naval and watch while taking in your breath, if doing this properly you should see your hand move up. then as you breath out press gently downward with your hand.
Do this whenever you feel up to it during the day or night. The more supine that you could get in the recliner or bed, the more effective this can be.. you have lymph nodes seated there in your groin and sitting up too much can cause a restriction of the lymph flow.
You can, after the breathing, place your hands lightly on your upper thigh, right where the crease is in your groin and lightly stroke upwards towards your naval.
I did this quite a bit post op and while it takes a while for the body to wake up and respond, it will, and it will help get things moving.
The reason this can help is because our lymphatic system doesn't use our cardiovascular system to help lymph fluids move.. no assistance from the heart pumping. Our breathing and our physical (muscular) movements keep it flowing.
