Could Arms, Stomach, Legs Lumps With Itching Be Due To Birth Control?

My name is Chelsea. And I have a question about my birth control. Ok I have been taking the birth control pill Tri-Cyclen for 17 days. After the second day of taking it I started to have these pumps pop up that would itch really bad. After a week I noticed that they started moving down my arm onto my belly in between my legs and now im my other arm. It has gotten so bad now that I cant even sleep at night. Can you please tell me if I need to stop taking them or what should I do?
