Based on comments from the cardiac surgery nurse practitioner, I wore a compression sock on my left leg most of the day yesterday, and for today’s dialysis session. After dialysis, I removed the compression socks and it appeared that the lumps have mostly disappeared. I then replaced the compression sock with a compression bandage for the next six hours and the lumps are almost all gone. Maybe using the compression socks/bandage is enough to push the blood/fluid out of the leg and I won’t need to get an ultrasound.
It’s been about two hours since I removed the bandage, I can see a hint of the lumps starting to reappear. Maybe if I wear the sock/use the bandage a few more days, the lumps won’t come back.
