Ask for pool physical therapy to start, if it is available to you. I was barely able to walk last July. I go to pool exercise class 3 days a week and am now able to swim 40 laps. I could do only 5 strokes to start. The swelling goes down after the class and other days a light work out with the exercise tools. I take my tape measure along to see just how much swelling goes. I was pleasantly surprised. Just light kicking floating with the noodle is helpful. Sometimes I use the steam room, sauna, or hot tub after the pool. I drink a bottle of water during the exercise and in the hot areas. This seems to help flush the junk out of my system. There are a lot of exercises on You Tube to do while sitting or with a chair at home to help swelling. Moving your ankles, feet, toes with legs up helps some. The gym I go to also has a light yoga class and chair exercise. They are helpful also. There are electric massage tables I use to help circulation. Different intensity settings. This helps some to just to relax. Ask for a guest pass to see how you like it. Go for at least 10 times. You will feel the difference. If you go, please share how it helped. I just know you will be happy you tried this.
