@jennifer1967 , my mother had Fentanyl patches for chronic pain. I always made sure to put them on a different part of her back each time. They didn't affect her skin. If your skin needs soothing, Doublebase is a very good emollient and made my Mum's skin lovely and soft. You can get it on prescription.
Regarding the ramp, we had one put on for Mum's wheelchair. They wouldn't build a concrete one as Mum was not working age so put a more temporary structure up but it has worked fine and now my brother uses it with his mobility frame. I am not sure what it is made of ( a sort of hard resin) but it's a sloping structure, very sturdy, and is fixed to the step. We also have a rail on the side. They gave us a portable small ramp to put inside to go up the step indoors. The council did this for us. It is not so much work as a proper concrete ramp but I think it's just as good. They can fix it quickly.
