Hi Sophie... I would recommend you have a friend either come with you, or at least come to pick you up/accompany you home in a taxi. You'll be fine, but you'll be a bit tender, and feel a bit vulnerable. Also your body may be a wee bit in shock, so you might be shaky and weak. Best to have someone with you... even if you feel fine, a bit of company or someone to make a cup of tea for you when you get home will make all the difference. I had a cyst removed last year, and another treatment under local anaesthetic and it was ok, but after doing the first alone I got a friend to pick me up after the second one and it was a relief. Even though I fell asleep as soon as we got to my place she stayed with me, and it felt good to know she was there. You'll be tender until a couple of days after your stitches are removed - just make sure to keep the wound clean, and rest, rest, rest is the main thing that will make you better.
Good luck, and let us know how you get on
