Hi @Maria45 & welcome to the community. Sorry you’ve had cause to join us but hopefully you’ll find it a useful place to be.
It is difficult for people to understand an invisible illness and unless someone has been in that position I guess it’s to be expected that they can’t. Don’t hide it though & be honest about how you are feeling.
Pain after a stroke is fairly common & has been discussed on this forum a few times. I have copied in a few links to some posts below. You can find more if you use the search function and just enter pain or post stroke pain.
I have also copied in a link to the Stroke Association leaflet which you may find usedul.
