I am very itchy in my inner ears, throat, nose, eyes, pallet, inside my head, cheeks, facial area. This comes with severe facial swelling, pain, tingling and numbness of the face. The swelling affects the facial nerve. I was recently ordered to stop using cortisone based nasal sprays (due to long term side effects) and was prescribed Zyrtec but it is not working. This is driving me crazy. The symptoms worse at night and I can't get any sleep. My nose is blocked, got the sniffles non stop and sneezing too. I am itchy and irritable 24hrs. I have also tried most home remedies but non effective. What should I do please
