Painful Lumps In The Sternum-throat Area. Growing In Size. Also Having Migraines, Muscle Spasms, Fatigue, Loose Motions. Advice?

I have had five or so lumps on my arms and legs for around ten years but in the last two years the number has jumped to more like thirty on the out side and a few i can feel only from the inside (these ones are in my throat right where it meets the sternum) . In the last eight months or so they have become very painful both to the touch and just shooting. They also are growing any where from 2x - 5x the size they started. And in that same time frame they have started turning black or dark purple. Also ive been experiencing severe migraines (about three a week), muscle spasms, fatigue, stiffness in hips and legs, watery loose stool, and on top of all else i am now unable to sleep for more than three or four hours at a time. I have had two of them removed and the they came back as angiolymphomas but my dermatologist believes i have atleast three types of grows goong on. I am haveing a very hard timr trying to find a GP doc to get me on the road to diagnosis. Any adive would be helpful. Thank you
