Something that helped my relationship was to completely stop talking about the P/N. My mother had it along with F/M and Parkinsons and I dreaded having to see her to the point I was totally stressed out before I even got there and I did love my mum however there is only so much I could listen to.
My partner started to get the same glazed over look that I used to get when she was with me. There was resentment on my behalf because she didnt understand but how could she? she isnt me and
DR SMITH gave a good analogy with the glasses. In Pain and not being understood = frustration = anger
I no longer ever ever mention it but she can see me wince at a 9 or 10 shock and can see me limp etc. When it gets really bad I go to bed but Never talk about P/N , whats the point?
Good luck , really hoping you can work through this.
