I have had this raised pimple like vein that occasionally throbbed ,for years.But now it hurts and throbs painfully and frequently.Twice during the night in the past year,i have had the must hurting and painful cramps in that leg that lasted for over 20 minutes!.Should I see a vein specialist?My family has a heart ailment history and I have high cholesterol.Other than that I am a healthy 52 year old active female.
