I m a 45 year old flight attendant. I had endoscopic sinus surgery 3 years ago. The past 2-3 weeks, I ve experienced extremely watery eyes, heavy post nasal drainage from nose and ears, as well as migraines combined with extreme pressure and pain behind my eyes and in my ears, and waking up sweating profusely with difficulty breathing. I take levocetirizine daily as well as receive allergy shots every 7-10 days since September 2016. Do I need different medication, to discontinue the allergy shots, or return to my ENT for re-evaluation? Please advise. Thank you... Sincerely,
