Lump and swelling

So, I discovered a lump really deep in my left armpit, with slight swelling and a lump/swelling just above collarbone. Make an appointment with doc, he examined me, and confirmed what I was saying,but he also said there is another lump in breast and top of breast is swollen. (Which i hadn't noticed) Now I have noticed that when I do the hands on hip examination my breast is kinda sinking in on bottom of outside breast .. that make sense.. 

Now to wait, but saying the back log for hospital/mammogram is big and could be up to around 4 weeks until seen.. I think I'm gonna go mad in this time xx
