Painful swelling? For the last year I've had very painful swelling in my legs.  I've also had terrible pain in my right buttock.  I don't know if the two are related but the both started around the same time.  I've gone to 6 doctors, but I have an HMO so it's a frustrating joke to keep getting passed along.  I've had blood tests, all negative.  Neurological tests.  Negative.  I am in great shape and play a lot of sports, but this started when I was playing a lot of sports in the tropics and not stretching or drinking gatorade.  I've cut foods out of my diet, do drink lots of water every day, have never eatten much salt other than drinking dt. soda.  If I go play soccer, when I talk my shin guards off, you can read the name of the sports company on my leg there is so much of an indentation.  Socks have become painful to wear.  Any ideas??

Summarized question: What causes  painful swelling in my legs and how can I get rid of it?
