What Causes Weird Sensations In Legs?

Hi, I am without a doctor at this time and for about a little more then a week I have had the weirdest felling in the inner part of my leg right below the knee. More in the left side then the right and the best way to explain it is it has no pain and it feels almost like a rubberband is around my knees. I am over 45 years old and about 50 pounds over weight so maybe it is a menopausal thing???? I have a sweet little girl that has CP and I am her everything. She cannot walk or talk so it can be hard on your body caring for even the sweetest soul. Should I just wait and see or maybe even see a chiropractor?
