What are some possible causes of pain and swelling in your left leg?
Standing or sitting too long may cause fluid buildup that leads to swelling of the leg, according to Mayo Clinic. The condition may also result from serious health issues including heart failure, thrombophlebitis, pericarditis, lymphedema and cirrhosis. It may also occur from chronic kidney disease, acute kidney failure or a reaction to prescription medications. A leg may swell as a result of inflammation due to injury such as a broken or sprained ankle. Serious conditions that may cause inflammation include cellulitis, knee bursitis, Achilles tendon rupture, gout and osteoarthritis.
