Foot pain and swelling at night is something many people with IgA Nephropathy experience. When kidneys aren't filtering properly, fluid can build up in the body — especially in the lower limbs like feet and ankles. This is called edema, and it can feel worse at night after a full day of being on your feet.

Foot pain and swelling at night is something many people with IgA Nephropathy experience. When kidneys aren't filtering properly, fluid can build up in the body — especially in the lower limbs like feet and ankles. This is called edema, and it can feel worse at night after a full day of being on your feet.

Here are some things that may help ease the discomfort:

- Elevate your feet above heart level several times a day, and try sleeping with a pillow under your feet
- Compression socks or sleeves can help push fluid back toward the heart and reduce swelling
- Gentle movement or massage of the affected area can also help move fluid along
- Check your diet — high sodium intake can worsen fluid retention, so reducing salt may help

It's also worth asking your doctor about your potassium and phosphorus levels, as imbalances can contribute to discomfort. If supplements are on your radar, always check with your doctor first — some can actually be tough on the kidneys or interact with medications.

This is definitely something worth bringing up at your next appointment, as persistent or worsening foot pain could signal changes in kidney function that your care team should know about.
