Could Lump On Collar Bones And Throat Be Due To Hormones That Loosen Joints During Pregnancy?

Hi. I was told after my first child that the lumps that are on my collarbone and up my throat are caused by the hormone that loosens your joints and ligaments and something has broken off? Im pregnant with my second child due in a week. The lumps have now grown, caused purple bruises where they are growing and are so painful it makes me cry. What are these and what treatment can i have to get rid of them. Please help!
