Every morning when I wake up, I sneeze a lot, almost non-stop. Also, I've noticed that my dark circles under my eyes are getting worse every day. Is there any connection between the two? What could be causing this?

The sneezing could be due to allergic rhinitis, and the dark circles could be a result of nasal congestion causing poor sleep quality. For the sneezing, you can try taking an antihistamine like Claritin (loratadine) once daily in the morning to help with allergies. To address the dark circles, you can try using an over-the-counter decongestant like Sudafed (pseudoephedrine) to help with nasal congestion and improve sleep quality. Make sure to also maintain good sleep hygiene and consider using a humidifier in your bedroom to help with any nasal congestion.
