Sorry but cannot figure out where I can read messages.

In the profile overview, it says I have 6 messages…a new one came in minutes ago, but for the life of me, I cannot figure out where or what I do to read them.

I'm pretty sure that I was in the area for messages at one point. It said no messages, although at the very same time, the profile box on the left of the screen said 5 messages.

I'm not being lazy, but could someone tell me where I find the 'read messages' button please.
