Thanks for your question. Your significant medical history suggests that you need to speak with someone about your problems, and that you will likely need long term medical follow up to make sure that there is not something serious causing your symptoms. It can be very difficult when you don't have insurance, but there are things that can be done to help. Most hospitals will have case managers and others who can work with people to help them get set up for some sort of state assistance or other programs to get reduced costs for their medical care. Almost everyone can qualify for some sort of assistance in most situations, provided that there is a financial need. While it can be hard to get through all of the red tape to find out who to speak with, your doctor
can often help direct you to the right people. In other situations, a free clinic may be available in your community and may offer assistance that you need. Leg swelling can be a sign of many different things ranging from heart problems to kidney problems, blood disorders, and many other things. It can be a sign of something serious. Please speak with a doctor soon.
