Pes anserine bursitis can create an aching, irritated feeling along the inside of the knee.
The pes bursa is like a small sac of oil that reduces friction where three tendons attach. When it becomes inflamed, it can feel swollen, tender, and “angry.”
A cortisone injection works like a concentrated anti-inflammatory — similar in purpose to ibuprofen — but delivered directly into the inflamed bursa.
Instead of circulating through your whole body, it targets the exact source of inflammation.
✔️ Reduces swelling
✔️ Calms irritation
✔️ Relieves pain
Combined with proper stretching and activity modification, this can significantly improve symptoms and restore function.
