Weird lump on shoulder - anyone else had one?

[SolidGoldBrass]

I've had a little Google, which was unhelpful and scary. It's egg-sized, squidgy, on the front of my shoulder, and it's been there for a week or so. It aches a bit. I do have osteoarthritis, is this just another bit of it?

Sounds like a cyst of some kind. It is worth having it checked out for peace of mind though.

Sounds like a lipoma to me, i've had one in the same place as you for 30 years. They aren't anything to worry about if that is what it is.
