Arthritis and small children

I’ve got a doctors appointment on Tuesday to find out whether I had rheumatoid arthritis. If that is negative I suspect that they might suggest psoriatic arthritis due to swollen joints in my hands and sore joints almost everywhere else. I appreciate that there might be medication etc that will help with the discomfort but I’m wondering whether anyone else is going through this whilst looking after two small children. They want to be carried, play games, run around with me and I don’t want to be a boring mum but it’s causing me so much pain. I’m hoping for some tips. x
