Hi Copilot 12,
I have read your question,
The eyes have been called the most sensitive organs in the human body. That is because they are with pain receptors—extremely sensitive, finely tuned nerve
endings that help protect these vital organs.
The Symptoms you said above do show the signs of sinusitis
or normal headache.But without physical examination and medical history ,it is difficult to come to any conclusion.
Pain inside eyes and itching are sometimes signs of allergy
due to pollution etc. contact lens
sometimes dont suit few people as well. Continues staring at computer screening , reading etc may also cause the same.
I recommend you to consult an ophthalmologist immediately for any further medical guidance.
I hope you get well soon.
