As above, our AMA guest here is a consultant in the HSE. I have verified his identity and that he is a consultant in HSE.
Hopefully his answers to questions will be a valuable resource for everyone and for that reason we are opening this thread for questions and a separate answers thread to keep all of the informative content in his answers together.
Please stick to this format for Qs & As as posts from anyone other than the OP in the answers thread will be removed.
ANSWERS can be found here.
Please note, as always do not ask for medical advice.
