What causes high fever with fainting inspite of clear test reports?
Patient: 12 yr old super fit girl having high temp 39+ for past five days. Many bloods done, both while having fever and not, chest xray, sugar levels, MRI, urine testing, throat swab, spit swab, nothing at all wrong. So do you have any idea what else could be causing this....in first two days she also had 4 fainting episodes, first one she was out for ten min and not responding to questions for another 5 minutes after waking up. Doctor: HelloAs you mentioned that all tests are normal , so hormonal imbalance is the main cause ( because her age is 12 years and puberty may the reason i.e. hormonal change and this is normal , not a cause of concern ).2nd reason of such cases may be stress or anxiety or tension ( may be of study ) .So in my opinion there is not a cause of concern and don't require any further investigation .Wait for another  4-5 days but if still fever persist then consult a gynecologist & physician and get their opinion.Hope this will be useful for you.
