What Causes Sweating, Sneezing, Itchy Skin, Tired Eyes, Fatigue And Frequent Urination?
Seems to be Allergic rhinitis.
Detailed Answer:
Welcome To HCM. I am Dr Anshul Varshney. I understand your concern.
Your symptoms are classically suggestive of Allergic rhinitis.
If your allergen test is negative that doesn't mean at all that you are not Allergic to something.
That's a probability test , it doesn't assure you finding of the allergen.
My advice for you would be getting a sugar and thyroid test done if not done yet.
Take an anti helminthic drug like Mebandazole to kill any worms in your body that might be causing an Allergic reaction.
I would also recommend you to discuss with your doctor to start you on Anti Allergics like Levocetrizine and Montelukast and see the response.
I hope it helps you.
If you have any further query, please ask me.
