First of all you've come to the right place! Everyone on here is so helpful.
With the bleeding after the treatment, the main thing to look out for is an 'off' smell as this is linked to infection. If the bleeding starts to get quite heavy (I know you can't compare to a normal period but if there is a lot of bleeding) then go to your gp and they will give you antibiotics for an infection, just in case.
I'm not sure about the type of local anaesthetic used as I had mine under general but someone else might be able to help. It may also be a good idea to give the hospital a call and explain your situation with the local anaesthetic last year and definitely make sure you mention it again at your appointment.
Regarding the bleeding; if it is bad enough to soak through 1 pad an hour then you need to get it checked out. I had that problem but it wasn't infection, just where they'd 'sealed me up' had come away somehow even though I'd been very careful.
I had the loop under local, and very glad that I did. I felt fine the whole way through and even after. Felt a little uncomfortable the next day but nothing major. I never even felt them do the injection! The most annoying part is that you get a bit shaky from the anaesthetic and you can't keep your legs still lol but that wears off quite quickly.
Hi there, I hope this helps. The local anaesthetic that's used at the dentist is usually lignocaine or lidocaine as it's sometimes also called and it comes
in strengths of 1% and 2%
im not sure which one they will use I. Your case but another local anaesthetic used commonly
is chirocaine 0.25% or 0.5% if I were u I would try to find out what brand caused the reaction last time so you can be prepared this time.
