Lymphedema is swelling that’s caused by a collection of too much lymph fluid. It usually happens in your arms and legs, but it can happen in other parts of your body, as well. This swelling may cause pain and limit how well the affected area moves.
Lymph is a protein-rich fluid that moves throughout your body in lymph vessels. It scoops up things like bacteria, viruses, and waste, and carries them to your lymph nodes. Your lymph nodes then filter the fluid to get the impurities out of your body.
You could get lymphedema for any number of reasons. There are treatments to help bring down the swelling so you feel and move better.
