Hi Susie
Its is quite common for this to happen.My wife had the same thing happen to her.The only advice I would give you is to keep away from lots of people shopping trolleys anywhere the public touches things card machines bank machines. Waah, Wash,wash,and wash your hands many times a day. Don’t touch your mouth or nose with your hands. (Sounds like Corna advice) but thats the simple answer to it all. They neutrophils will come back don’t get to het up about things. I know the is easy said than done. If any children around you have colds keep away from them as well. Don’t shake hands or kis etc.
Good luck
Matthew
