I have had type 1 diabetes for 15 years and am experiencing some pain and discomfort in my arm. It is only in one arm and the symptoms get worse in the evening. The pain will wake me up in the night. My arm tingles, feels very tight and my fingers swell. I have not noticed any swelling in my arm and my feet are ok. Thinking I might have diabetic neuropathy, but not sure. Any thoughts or advice?
