Hello, I have a dull pain in my legs during night for almost 2 years. Somehow, I manage to fell in sleep, and then, I wake up around 4 ot 5 am. The pain in my legs is according by heaviness in my heart. My legs feel very warm and I feel like when I move them to the colder area on my matrass, they feel better. The moment, they get warm, the pain comes back. I stopped sleeping. It becomes my nightmare... They doctors think that this is a restless leg syndrome, but the pills they prescribe from this problem, don t help. Are there any tests I can get to have a clear and correct diagnose? Ultrasound, etc.? Thank you! Victoria.
