Ive been type one since 1990..have had same pain you describe in my left foot but was diagnosed with plantar fasciatus..extremely painful nd debilatting..had more pain on opposite side to foot and after much pushing for an answer and a scan and xray was referred to a rheumatologist who diagnosed me with osteo arthritus and fybromyalga all over my body whivh is where the pain now is..fingers thumbs wrists toes ankles hips neck and shoulders btw have had frozen shoulders in both sides and believe all this pain is related to my diabetes tho no one will confirm.. im deptessed and stressed with pain and now see a cb psychologist as well as the pain management clinic . I feel like the tin man and some days can hardly move....nothing they can do apparently..
