12 months post op thigh-lift, stubborn edema or secondary lymphedema? (photos)

Hello, thank you for reading my concern. I had thigh lift surgery with liposuction 12 months ago and everything went great. The only problem is that both thighs still have the initial post-surgery edema. I've been mostly sedentary this past year but I haven't gained any weight. A week ago I visited the surgeon that performed the procedure and he recomended lymphatic massage. Should I also check with an angiologist? I have a fear it's secondary lymphedema.
