Thanks suunto. I've had a look inside the bumps and can't see anything except a dry-ish white substance - can't see anything actually living inside. When I went to pick the leaves there were many ants crawling over them which are the only insects I have seen near them. I've posted a photo of the underside of a leaf.

They do look like leaf galls from the photos you directed me to. Any ideas how to deal with them ?!
