@Hey Jude Hello! Sorry it took a bit to respond. What helped the most was drastically reducing my exercises, icing it as often as possible, and keeping it elevated every time I sat or laid down. I also started doing some lymphatic massage which I think helped (a simpler version would be simply doing upward gentle strokes to stimulate flow, but there are some more in depth techniques that can be found online or with the help of a massage therapist). Also, make sure you are taking in plenty of fluids, this sounds counterproductive but you need to have enough going in to flush anything out. Compression stockings for me seemed to make it worse so with permission I went without and wore sequential compression cuffs on my legs instead.
Time and patience, rest, and try not to stress about the swelling. Remember that your ROM will come eventually whether you are pushing exercise or not, and pushing it = angry tissues/inflammation = more swelling. Also FWIW, at 12 weeks I still have days where that leg swells HUGE, just depends now on my activity that day. Best of luck to you and I’ll be watching your progress!
