I agree with Curt about you needing to work with a doctor to help your problems. Please ask your doctor to run a ferritin level on you. If your ferritin level (storage iron) is in the lower range of normal, it could (not absolutely, but could) contribute to the severity of RLS. Since you are bruising easily and that's a possible sign of anemia, it wouldn't surprise me if ferritin is low. Your doc may want to do complete iron studies on you. If a low ferritin is not an issue with you, the meds may be your best recourse, although they should be used conservatively. Please do let a doctor work thru what's best for you.
What a lovely name, KatieMarie!
The best thing you can do is to see a doctor. There are meds specifically for restless leg syndrome that will really help you. Anemia can cause bruising and it's a very common condition for teenagers and young women. A blood test will easily show if you are anemic or not. I don't know about the migraines - there are so many causes. Your doctor can help sort this out and also there are meds to help reduce the effects of the migraines.
Let us know how everything comes out!
Best of luck.
Curt
