Medical Forum
This not an emergency service, in case of a diving incident, please contact your local Coastguard, nearest recompression chamber or emergency services.

All questions are answered by Dr Oliver Firth, one of the doctors at the London Diving Chamber. Dr Firth has had a wide variety of experience as a doctor in both the UK and Australia. He writes regularly for ‘Sport Diver’ Magazine and gives talk on hyperbaric medicine.

Because of the confidential and sensitive nature of advice given in the medical forum, questions DO NOT post direct to the forum page but are sent to the doctor for his comment and reply. Once a reply has been sent, both the question and answer will post to the forum page.

Questions are shown in Red and the answer from Dr Firth is shown in Blue. Once an answer is posted, it is then possible for other users to post additional comments, these are shown in black.
