Swelling above collar bone for few months

Hi, for the last few months it has looked swollen above both collar bones, but now it is quite raised above my left collar bone. I showed it to my husband, but he didn't seem too concerned.  

I put it down to gaining weight, or that perhaps my body was fighting something off as I have had pains in what I think must be glands ,  but now with it being even more noticeable and that I think i have found a small lump in my breast, I'm thinking it's time I saw somebody about it. 

Has anyone else had this and it's been something minor? Cysts or something? Going to try and get a telephone appointment tomorrow. Thanks
