The more difficult thing is to ensure the wound is clean and that there is no damage to other structures.
I wouldn't recommend DIY suturing - to do the job properly you need a good light, local anaesthetic, sterile monofilament sutures of the correct gauge which come with an attached curved cutting needle, a sterile stitch set, and ideally an assistant.
Agreed, which is why I eventually went to A&E. I was a bit worried in case I'd unknowingly done some damage.
