Hi, I Am 49 Years Old And I Am Experiencing

Hi, I am 49 years old and I am experiencing a burning/aching sensation in my thighs and legs mostly at night. I also have hot flashes and my monthly cycle is very in consistent where it used to be "clock-like" regular. I think I may be entering menopause and of all my symptoms, the only one that bothers me is the leg problems. I've tried increasing my Potassium, taking Ibuprofen, naproxen sodium and am in the process of cutting out my soy intake (I am a vegetarian). Is there anything else I can do to relieve the pain in my legs and thighs?
