I found bumps above my collar bones? What could they be?

Alright, so a little background:  about six months ago, I was sitting at my desk in my home office and somehow, I discovered a little rubbery bump on the inside of my arm near the elbow.  Upon further self-examination, I found I had the same rubbery bump on the inside of my other elbow.  They're both somewhat rubbery and movable.  I'd say both are each size of an ear bud off of a pair of in-ear headphones.

I went to a local walk-in clinic and the doctor there felt them and said they were lipomas.  He prescribed me some antibiotics for a sinus infection.  The bumps have stayed the same size.

Fast forward to about a month ago (two months after I found the bumps by my elbows), I was laying down on my couch at home and was rubbing the area about halfway between my shoulder and neck and I came across a very hard lump that almost seems to be sitting on top of my trapezius muscle, or whatever the muscle is called between the neck and shoulder.  Again, upon further self-examination, I feel the same very hard lump in what seems the same exact spot on the opposite shoulder area.

At first, I really had to dig deep to feel the bumps...hunching my shoulders does helped me find the bumps easier before.  Now, I can think I feel them when my shoulders are relaxed.  Am I being paranoid?

Hi, for lymphoma to be so symmetrical like that would be very, very unusual.

When you say that the trapezius bumps are "very hard", do you mean "rock hard"?
