I am T1 pumper, it I see a lot of diabetics with foot pain, a lot can be the shoes/trainers, the way you walk, it I have plantar fasciitis also I have neuropathy in my right foot, the plantar can be alleviated by rolling a can of beans under your foot, backwards and forwards, stretching also helps, it does come and go, mine has gone for a while now ( the plantar fasciitis not the neuropathy)
I too am waiting to go on mounjaro as I’ve ballooned since retiring!
Let me know how you get on, oh I did co-codamol as mine was very painful
