Hello. Thank you for asking at HCM. I went through your history. I would like to make following suggestions to you: 1. Regarding your sneezing symptoms, I would suggest you to take regular montelukast and levocetirizine for at least 2-4 weeks (depending upon response). If you are already taking it, I would suggest you instranasal corticosteroid spray. 2. Please do not smoke if you smoke. Please avoid exposure to dusts, smokes and air pollution as much as possible. 3. Daily nasal cavity irrigation with saline nasal sprays also will help. 4. For identifying the cause of sneezing, I would suggest you to consult an Allergist-Immunologist who will advise you allergy testing. This will help you identify substances causing symptoms to you as well as measures to avoid them. 5. For black spots, usually black spots on face are not due to sinus/allergic diseases. They may be due to effects of polluted environment and skin problems. Of course, allergic rhinitis/sinusitis can cause blackish discoloration below the eyes, but not black spots on face. Hope above answers will be helpful to you. Wish you the best of the health. Should you have any query, please feel free to ask at HCM. Regards.
