Barrister lying and I'm asked to take oath??

I'm a LIP and I recently had a situation in court where I said something to the other side's barrister in the pre hearing meeting. I had my McKenzie friend with me. The barrister then went into court and told the judge a different version to what I actually told him. When the judge later asked me about what was said and realized what I said was different she said she was now presented with a problem (because my version was different to what the barrister just told her). She got really upset and asked whether I was prepared to confirm what I said under oath, which I affirmed. I was sworn in and asked again and I relayed again what I said previously. I asked her what was the significance of all of that and then she garbled something, but I felt the judge was not being straight with me.

I now thought about it carefully subsequently and it's clear that the barrister lied to the judge and I had a similar experience with the same barrister that misconstrued what I said. However, this time I have a witness to what I said and the barrister clearly lied and it was a big enough deal that the judge went through the whole effort to swear me in.

I'm now thinking very hard about whether I should be doing something about it and if so what? Surely a barrister cannot just lie in court like that?
