My grandfather is having health issues. Last week, he was complaining about being tired, sleeping a lot and acting confused (can't find his way to the bathroom, that kind of stuff). He had a very quick pulse and got some medicine at the beginning of the week to treat this, but it took a while before the medicine started working. The exceptionally hot weather of last week probably didn't help his condition either.
At the same time, my grandmother seems unable to understand that some pills don't immediately work, but require a while to fully kick in. So she would be calling my parents 2/3 times a day saying my grandfather was still not doing any better, but he had taken his medicine so he should feel better, right?. A few times, my parents wouldn't be near their cellphones so she'd be calling the house phone or my cellphone, and I'd be stuck with trying to calm her down.
The conversations were mostly similar: One of my parents had promised to come later, but could they please come now because my grandfather was still not doing better. I tried to ask whether things were getting worse or find out what happened to prompt the call but basically got no coherent answers, just repeated assertions that I should attempt to contact one of my parents to come immediately.
For the first one, I panicked and overreacted by calling my father afterwards, so he could talk to his mother about this. Surprisingly, even though she was acting like everything was getting worse, when dad dropped his work to visit, both my grandparents said that my grandfather was actually doing a little bit better.
For the second/third one after that, I tried to reassure my grandmother that my parents would be there at the agreed upon time, that if my grandfather was actually doing very badly she should call the emergency number, that they'd be there sooner than any parent, and I tried to reassure her that if grandfather wasn't obviously getting worse, eventually the medicine would kick in.
It seemed to leave her more agitated than reassured though, all the phone calls ended with grandmother hanging up the phone with a frustrated remark (something like 'Never mind then') and then continuing to try and call my parents at their cellphones. Mostly, this resulted in my parents dropping what they were doing or again calling me and sending me over (my grandparents live just a few streets away). All the times, it turned out grandfather was doing as fine as circumstances would allow.
Grandfather is doing a bit better now, but I'm expecting the next time to be close around the corner, so:
When getting a call from a panicked grandmother, how do I calm her down without her dropping the phone call in frustration and either her or me having to bother my parents?
For those that care: I'm 28 and currently living with my parents, so I'm not some young child confronted with this, luckily.
