Do I need sedation?

I’m due to have my impacted wisdom tooth removed at the start of June. It’s been agony and I’m on antibiotics for an infection. If I want to have sedation it will delay treatment by at least another month, unless I decide to pay private which I want to avoid as it’s a lot of money. I’m in the UK. Do you think I’ll be ok just to have a local anesthetic or is it worth waiting for sedation too? I’m not in as much pain now I’m on antibiotics but I know it could come back any time.
