Restless legs, hips ache and generally don't feel right, getting cold chills temp is 37.8 what could this be and what should i do?

Iron deficiency: It's possible you have iron deficiency which can lead to restless legs and perhaps some of your other symptoms. It could also be a low thyroid. I wonder if you're eating properly or if you have heavy periods which could explain some anemia/low iron. Good if you can get some labs checked - that's what I'd start with - a complete blood count, iron tests, and thyroid function. Hope you feel better.
