Hello. My dad had swelling in both his feet, ankles and legs. The worst part lasted a couple weeks. However, I am not sure whether this was from chemo, or the other problems he has going on.
You want to make sure you tell your doctor about that, because edema can be caused by different things.
They will probably tell you to elevate your legs when you're sitting down, higher than the level of your heart. Do you have it in both legs? Have you been eating well?
