Hi,
Thank you for posting your query.
Your symptoms are suggestive of pre-
syncope.
In this condition, the above mentioned symptoms happen due to transient lack of blood flow to brain. This in turn can happen because of strain, exhaustion,
fatigue, low sugar, infection, etc.
If all above are normal, then a cardiac evaluation may be useful.
Please get back if you require any additional information.
Best wishes,
