I had a pacemaker put in 2 months ago butt it flipped, so the had to remove and put another one in. My left leg has been edema prone since then. I swells more in the after noon and is very painful, especially under the back of knee. My doctor has put me on water pills, but they are not answer. Please help. I have been to vein spec, and had scans for DVT, etc. Thank you.
