Don't know if this is pertinent to your recent 'setback', but I was at Mayo a couple of weeks ago for what I considered an important appt. For 2 days prior and a week after, the crusty nose & some blood came back. Numbers weren't affected, but my stress level was...thus, I believe, the reaction. Remember everyone...there is no cure...so stress & other situations can create some of the more common WG reactions again. Best to all.
