Actually wait, yes. Back when I was at the worst of it, I spoke to some people at Ergo Canada: https://ergocanada.com/ https://ergocanada.com/ They steered me towards the handshoe mouse, and also guided me through trying those dome type keyboard. (Didn’t work for me but the staff were super helpful) I don’t know if they do US sales but they have every class of ergonomic product under the sun and fantastic experts who were focussed on helping rather than selling. They may point you to a US partner, a consultant, or be able to ship to the US. (If they do give you advice about products I’d try to buy with them rather than shop elsewhere, they’re very helpful)
