Maybe posting too late but too expand my answer.
I agree with seashells. I am a nurse. I am frequently horrified at the number of threads where people are seeking advice for what sounds like acute problems.
Whilst I appreciate that chatboards can be useful as a form of support for people who are pregnant o living with a diagnosed chronic condition, i do not think they are appropriate for undiagnosed acute ailments.
As previously mentioned mn is unable to verify the professional qualifications of people.
From a professional viewpoint it is impossible to accurately diagnose people over the net. they need to be seen in person to be assessed properly and treated or advised.
Whilst there may be some merit in having a first aid section/ I think it would be more useful to link to the NHS websites.
The problem with having your own videos is that you have to keep them updated and are then potentially liable for any outcome when people use them.
In a real first aid instance, I would hope people would ring NHS direct for advice or call 999.
Tbh I would rather not see people asking for advice for undiagnosed symptoms on this board at all(or any other). The NHS is free at the point of contact it is staffed by qualified professionals who have access to appropriate treatment. I suspect that's wishful thinking though.
It may be useful to liaise with the NHS to have list of symptoms to remind people what er really not appropriate symptoms t seek advice about on here.
Such as; difficulty in breathing.
Fever with unknown cause or getting worse.
Burns
Non feeding infants.
I'm sure there's more if anyone wants to add t that list
