Sore Leg

I have been working straight for almost 3 weeks and my job is mostly manual every time I am assigned at housekeeping, on the other side I love it because there are plenty of extra bucks from tip besides my pay, but I hope my leg won't complain too much, most of the time I experienced sore leg and it felt mostly like a restless leg syndrome, I don't wanna visit the doctors because I don't have a health insurance and it's gonna be expensive. I am hoping I 'll be able to know what is the cure on this one, if I need to hang my leg maybe that's the cheapest way right? If you are one of the million people who experienced restless leg syndrome and sore leg most of the time, please let me know what do you do when it bothered you? Is there a kind of medicine for you to prevent it from attacking again? Please help and let me know, just add a comments in this post.
