Can happen at any time. Severe itching outside and inside of nose that can last 3-5 hours. Was taking Hydroxyzine 25mg caps that worked. Insurance will not pay for that anymore so was put on Levocetirizine 5mg. one week ago. I have had the itching one time since then.
I think anxiety brings it on (not sure), but I would rather have my nose amputated than live through this as it was happening almost every day. I used scissors and knives to stop itching and ended up with a bloody, scabby ugly nose! It is a living nightmare and effects your life greatly.
