So sad this has happened.Shingles can be extremely painful as you describe.I had this and can confirm this personally.
Was she given antiviral in time to shorten ythe attack?
Yes
what do the elderly infirm people go through if we are not watchdogs.I found unacceptable practice where a decimal point was misread and five times the ammount was given to a loved one...they protested to no avail..and again it was a doctor friend who challenged...but everyone does not have that as backup..so I am on red alert when others give medication.
agency staff cause me the most concern where no affiliation exists and are paid by the hour..gone the next night
so when any family/friend is in a residence or ward I vist and stay around..
when a nurse is helful I show appreciation and know this is like barter...but its the loved one that matters.
