10 ALS Symptoms
Symptom #6: Swelling of the Feet and Legs
Various mechanisms help the blood circulate through the body. An obvious example is the heart, but there are numerous others. Other mechanisms include valves that prevent the blood from being pulled down and muscle actions that help push the blood back up through the body.
Weakened muscles lead to poor blood circulation, causing the blood to pool in the feet and legs. This leads to swelling, which can be uncomfortable and make it difficult for people to wear shoes and socks.
