Does anybody else has primary lymph edema of the left leg? Dr's. say mine is from an unknown cause.?

this showed up at age 12 or so. im now 42 and want this gone. doc's say i'm lucky, it looks good and under total cotrol.i did the manual lymph drainage wraps/mage. i'm really tired of 2 legs that are different sizes. ive had 4 kids and it still looks good. maybe i should just be happy.
