My 18 year old daughter has suffered for the last
A Neurologist should be appropriate as a consultant.
Hello and welcome to 'Ask A Doctor' service.
I have read your query and here is my advice.
Since the cardiac problems are cleared out and seizures are excluded, in my opinion, neurologically mediated presyncope should be considered.
Besides the tests done before, a tilt table test should be done.
I think in such a case, a Neurologist as a consultant should be the one who can evaluate correctly if your daughter's condition allows her to swim or not.
Hope you found the answer helpful.
Let me know if I can assist you further.
